Humanity has survived almost unimaginable challenges over the past 5,000 years of documented human history. From war, famine and natural disasters to the first global pandemic in the last 100 years, more often than not, people have relied on one another to survive and thrive again. As the industry association representing the global microelectronics industry, SEMI has similarly made collaboration and community integral to the fabric of its organization. From helping members to succeed through the COVID-19 pandemic to facilitating member-driven industry standards around environmental health and safety, materials, and manufacturing capabilities, this approach shows members that standing together is better than standing alone.On the eve of the 50th annual SEMICON West (July 20-23, 2020) — the first virtual edition in SEMI’s history — I spoke with SEMI’s vice president of technology communities, Michael Ciesinski, about the role of SEMI in tackling big challenges through an active member community intent on solving problems through collaboration.SEMI: How long have you worked with SEMI and in what capacity?Ciesinski: In January 2016, I started my second tour at SEMI when FlexTech, the industry consortium I’d been leading, became SEMI’s first strategic partner. Nearly two years into that role, SEMI President CEO Ajit Manocha asked me to form Technology Communities to engage members with common interests. After FlexTech, we brought on the Fab Owners Alliance, then MEMS Sensors Industry Group (MSIG), and later the Electronic System Design Alliance (ESD Alliance).SEMI now has more than 20 communities in all, including Smart MedTech, Smart Data AI, Smart Manufacturing, Electronic Materials, and Integrated Packaging, Assembly and Test.SEMI: What is your role with Technology Communities — and how do members stand to benefit?Ciesinski: The leadership of Technology Communities ensures that SEMI’s benefits and services align to our members’ interests so we can provide member benefits that matter most. This spans forming communities where people hold common interests (e.g., advanced packaging) to facilitating standards that will promote intelligence in manufacturing (e.g., data standards for AI and machine learning) as well as providing R D funding.I’m especially proud that over the past three years, SEMI has brought more than $40 million in R D funding to our members, with most grants in the $500,000-$1 million range. We’ve been especially successful in securing funding in flexible hybrid electronics (FHE) through U.S. Army Research Laboratories (ARL), a model we first developed through FlexTech.Two recent recipients of FHE funding, GE Research and ITN Energy Systems, show how the grants are spawning partnership opportunities among commercial enterprises, R D organizations and universities. In developing lightweight, non-invasive wearables, including a human-performance sweat-monitoring patch that remotely analyzes sweat to detect hydration levels and other vital signs, GE Research is using key components such as sensors and lightweight batteries in its designs.ITN Energy Systems designed a flexible all-solid-state lithium battery that’s printed on light, flexible substrates to power small and incredibly thin applications.Universities are also benefiting by plugging into the SEMI ecosystem. In fact, 40-50 percent of funded projects are seeding commercialization by universities. This is another validation that SEMI’s collaborative, community approach to microelectronics is working.SEMI: Position, Timing and Navigation (PNT) is another hot area where SEMI has secured ARL funding. What makes this funding different and why is it important?Ciesinski: The PNT grant makes ARL funding available to the MEMS Sensors Industry Group (MSIG) members through SEMI for the first time. If you’ve ever lost GPS signal while coming out of a tunnel, you know how frustrating that is. For us, that’s an inconvenience, but for a healthcare worker in a remote location who’s waiting for a delivery of medication by drone, it could be life-critical. While that’s just one example of why we need PNT to operate when GPS isn’t available, I can imagine dozens of other important dual-use cases, including autonomous driving.SEMI: How else do Technology Communities benefit under SEMI?Ciesinski: Technology Communities need access to diverse resources to spur continuous innovation. Electronic Materials Group participants, for example, need to stay informed on regulations coming out of Asia, the U.S. and Europe that may affect their businesses. Where else other than SEMI can like-minded stakeholders congregate with people up and down the supply chain to determine whether industry-wide action is needed on regulation?SEMI: What is the importance of SEMI’s global footprint?Ciesinski: I’ve worked with many associations and managed major industry consortia. The clear advantage of SEMI is our global footprint. And that’s vital because microelectronics is a global industry involving a multitude of stakeholders that play essential roles in the supply chain.Let’s say you want to discuss EU regulations on hazardous chemicals. Rather than decipher these complexities alone, you can pick up the phone to speak with someone on SEMI’s European team to learn what’s critical.What if you’d like more information on the 20-plus new fabs that are going up in China? You can explore that question with our SEMI China or SEMI Industry Research and Statistics teams.SEMI: How has SEMI evolved over the years?Ciesinski: SEMI has a long history of providing what the industry cares about. We started in trade shows and pivoted to industry standards. We began with small silicon wafers and wafer carriers, and now within the span of 50 years we’re working on data-format standards that will support the application of AI and machine learning (ML) in the semiconductor industry.While highly varied today, data-format standards will help component manufacturers refine processes to create more efficient solutions. This ARL-funded program, which pairs SEMI members with the grant recipient, Cornell University, may offer dramatic gains in the productivity of semiconductor manufacturing.SEMI: How does SEMI’s approach to COVID-19 reflect core values of collaboration and community?Ciesinski: Together with Ajit Manocha, CMO Terry Tsao and other team members at SEMI, we pulled together a task force to help SEMI members navigate the pandemic.We tapped two existing groups, Environment, Health and Safety (EHS) and Information Technology Leadership (ITL) from the start, documenting their strategic and tactical approaches to help all members through the COVID-19 resource section of our website. The EHS section provides tips on facilities and meetings, employee policies, business travel and communications, while the ITL section lists insights on computing hardware for staff, licensing, networks, security and employee policies.Our EHS leadership team, which includes Entegris, Axcelis, Versum, and Intel, immediately started sharing best practices for sanitizing facilities. As a result of team meetings, SEMI EHS shared best practices on keeping the workforce remote and guidelines for returning people to work safely. From securing PPE and safeguarding employees and visitors by performing thermal scanning to outlining communications around potential employee exposures, EHS has provided meaningful resources for the benefit of all members.SEMI also took immediate steps in the area of advocacy. Our advocacy team in Washington, D.C., together with regional SEMI presidents around the world, have ensured that semiconductor facilities were and still are considered essential businesses in the U.S., Europe and Asia. That’s because microelectronics are foundational to fighting the pandemic.Microfluidics are critical to the Reverse Transcription (RT) Polymerase Chain Reaction (PCR) tests most commonly used for COVID-19. Sensors are embedded in the pulse oximeters that allow patients and healthcare professionals to monitor a vital rubric: oxygen saturation level. If oxygen saturation level drops into the low 90 percentiles or below, it may be time to go to the hospital for treatment.Microcontroller units are essential components in a wide range of hospital equipment, including the ventilators that may make the difference between life and death in the most seriously ill patients.SEMI: How can the ingenuity realized through microelectronics continue to help us tackle other big problems? Ciesinski: We have MEMS and sensors to thank for distributed intelligence, giving us the ability to put sensors anywhere, locally based in the field or in the packaging house.Food production is a prime example. Leveraging miniaturized wirelessly connected sensors, we can trace food through the entire production lifecycle, from the seed in the ground to the food in the warehouse and, ultimately, to the product that lands on the table.From larger enterprise such as IBM Food Trust to small startups, we’re using MEMS and sensors to improve crop yields so we can feed a human population that’s growing each year.There’s a sustainability piece as well. We’re using MEMS and sensors to reduce the amount of fertilizer or other nutrients or chemicals in the soil. That’s good for the environment and for the agricultural workers who labor in the fields.MEMS and sensors can also condense the time it takes to perform a specific task, conserving human resources.SEMI: Where do you think SEMI will go in the next decade?Ciesinski: Ten years from now, I believe we will still have our global footprint in place. I expect it will expand, particularly in Asia.We may also expand into new areas such as Latin America and Central America, which would provide at least two major benefits: People working in microelectronics would, I hope, have access to better quality of life. And diversifying the supply chain would allow nations and regions to have more control over the products they need, from PPE to medications, which may help us to better manage through the next pandemic.I am also hopeful that SEMI will be on the leading edge of helping our members communicate in much different fashion from what we have today. We’re already expanding beyond the paradigm of in-person meetings for standards meetings and conferences. As we move forward, I think we’ll see a hybrid solution to doing business, combining in-person meetings with virtual conferences and digital content that’s available 24/7.Whatever changes we see in SEMI, I’m confident that we will continue to see a global footprint in an industry association that prioritizes connections among members.Engage in the SEMI experience at upcoming SEMICON WestRegister today to hear from keynote speakers such as environmental advocate and former U.S. Vice President Al Gore, futurist and author Steve Brown, and IBM Research senior vice president and director Dr. John E.

The march of innovation in semiconductor microfabrication technology over the past 60 years has produced electronic devices and information systems that have transformed industries and lives around the world. And while advances in chip technology continue to make it possible to collect, transmit, store and process more data for a rapidly growing universe of applications, the pace of innovation is now facing strong headwinds. Powered by chip innovation, data centers have become massive centers of information processing but, on the downside, enormous consumers of electricity. Today, the power-hungry hubs account for five percent of the world's electricity usage, a proportion that is growing every year, raising important questions about sustainability. Compounding the challenge, the pace of Moore's Law, for decades the engine of electronic device and information system innovation, has slowed. While the research and development of state-of-the-art semiconductor fine processing technology remains robust, developing the advanced manufacturing technology for mass-producing more sophisticated electronics devices is becoming harder, as is ensuring business profitability."It has become difficult for semiconductor technology to continue to evolve as it has in the past," said Akira Minamikawa, Research Director of Technology Research at IHS Markit, who moderated the Semiconductor Executive Forum – View by Top Two in the Era of Digitalization on opening day of SEMICON Japan 2019 at Tokyo Big Sight. Held at the SuperTHEATER, the forum featured Terushi Shimizu, representative director and president at Sony Semiconductor Solutions, and Atsuyoshi Koike, president at Western Digital Japan, two industry powerhouses that could figure heavily in the future of digital technology. SuperTHEATER, the main stage at SEMICON Japan 2019 Image sensors evolve to become eyes of AIImage sensors are becoming eyes of artificial intelligence (AI) and intelligent systems that monitor people and events worldwide, collecting data that one day could help puzzle out growing social challenges such as energy conservation and traffic congestion. With 51 percent market share on the strength of its industry-leading technology, Sony Semiconductor Solutions dominates the image sensor market. Despite last year’s global semiconductor industry slump, the company’s “business continues to enjoy strong growth and we are very busy,” said Shimizu, who attributed the company’s robust performance to the rising importance of the social role of image sensors and the expanding number of applications they support.The success of the company’s image sensors can also be traced to its division of the image sensor market into two application categories: "Imaging" focuses on capturing beautiful image data, while "sensing" aims to collect data that accurately describes the state of a subject and its surroundings."In 2019, sales of imaging products for smartphones grew rapidly,” Shimizu said in his market overview. “This is due to the average annual 15 percent growth rate of multi-camera smartphones, with some phones today featuring seven cameras, and an average annual growth rate of 20 percent in sensor size to produce higher image quality."But Shimizu cautioned that Sony Semiconductor Solutions doesn’t expect the smartphone sensor market to maintain that fast growth rate."The imaging market is expected to grow until 2022, but after that, the sensing market will drive market growth,” he said, adding that the company’s “capital investment plan is based on this scenario."AI will be key in catalyzing growth of the sensor market as integrations of AI processing engines and sensing images grow in sophistication to capture images undetectable by the human eye, Shimizu said. AI will extract insight from captured image data. For its part, Sony will apply its layer stacking technology to sensing products."By stacking an AI processing engine, we want a significant portion of the recognition processing done within the sensor chip," Shimizu said.One sensor the company already offers collects in-depth information for indirect time-of-flight (ITOF) 3D ranging for new user interfaces relying on autonomous or gesture control for robotics. The sensor “was first used in smartphones in 2018 and saw widespread adoption in 2019," Shimizu said.Sony Semiconductor Solutions plans to focus on developing new sensors for integration with their ultrasonic cousins. Aided by optical deflection technology, the sensors will be used for product quality inspections during manufacturing.With the company’s growing strengths in sensor technology, it hopes “to increase sales of sensors from a few percent of the company’s total sales in 2018 to 30 percent in 2025,” Shimizu said, pointing to its goal "to capture 60 percent share of the image sensor market by 2025."Data as one way to spread happinessAt the heart of consumer devices such as smartphones and computers and also cloud servers, NAND flash has made it possible to process vast troves of data anytime, anywhere. In recent years, the technology has enjoyed stronger adoption for use as the storage medium of choice for edge computing, stationed between end devices and the cloud to help streamline data utilization. But the technology isn’t merely about making smarter use of bits and bytes."We would like to promote the technology development that can support the use of data to bring happiness to people around the world," Koike of Western Digital Japan said. The company calls data that contributes to individual happiness and helps solve social issues "data for good" and, like the Sony Semiconductor Solutions bifurcated classification of the image sensor market, categorizes information into “big data” and “fast data.”For example, big data can leverage AI to drive dramatic improvements in the interpretation of test data and, ultimately, the diagnostic accuracy of mammography for breast cancer screening, aiding in early detection to help save lives, Koike said. Fast data can be harnessed to analyze data collected from a manufacturing equipment line in real time to improve production efficiency. The company’s plant in Yokkaichi, Mie Prefecture, which the company operates in cooperation with Japanese memory manufacturer Kioxia, already uses fast data to bolster production.More NAND flash innovation and greater supply capacity are critical to developing "data for good," Koike said. "It is difficult to expand clean rooms at the same pace as data usage grows. In order to continue to advance technology and enhance supply capacity, we need to adopt new ideas for building production lines. We need a smaller equipment footprint, shorter cycle time and higher throughput."Semiconductor market shows signs of recoveryIn their discussion of the short-term outlook for the semiconductor market, Shimizu and Koike pointed to the importance of strengthening the talent pool of Japan’s semiconductor industry as global competition heats up with China’s pursuit of semiconductor independence and the industry pulls out of the 2019 slowdown fueled by weak memory prices. While Sony’s business has been buoyed by strong image sensor demand for smartphones, the devices “did very well, but other applications didn't," Shimizu said. Even the image sensor market stagnated.Despite the 2019 slump, market conditions and capital investments by semiconductor manufacturers have been on the upswing."In the second half of 2019, the Chinese market showed signs of recovery triggered by 5G,” Shimizu said. “In 2020, this movement is going to be in full swing around the world and we will be busier than last year."Koike agreed: "The semiconductor market for data centers will recover with 5G. The hard disk shortage is already an indication of a recovery, a turnaround that will undoubtedly extend to solid state drives (SSDs). In addition, advances in autonomous driving technology will ensure continued growth of the automotive semiconductor industry.”Japan should embrace international competition, not fear China's pursuit of chip independenceIt's no secret that China is investing heavily in its semiconductor development capabilities to move up the microprocessor value chain. Minamikawa posed the question: How should Japanese chip companies navigate the shifting regional balance of power? "It is natural for China to strive to establish domestic procurement of semiconductors that are fundamental technologies for various industries,” Koike said, “I think the efforts of Chinese companies are outstanding in that they are not pursuing short-term results, such as improving yields in the near future, but are making efforts with an eye to achieving results in 10 years. Japan has a variety of options including working with China to create joint ventures and competing head-on. Regardless of which choice we make, however, it is imperative for the survival of domestic companies that Japan maintains its technological competitiveness to remain ahead of China."Shimizu said that Sony’s “Chinese customers are quick to take action and study extremely hard. We often have opportunities to share our roadmap with them and explore innovation opportunities together. Before, they were passive and relied on us for insights into new technologies, but now they are more assertive and I sense that they will start to drive innovation.”Koike added that "although Japanese companies often talk about business globalization, neither Chinese nor American companies say much about it. While global expansion is a major requirement for business, I think Japanese companies need to focus more on the Japanese market overall, not just when they think about the growing competitiveness of Chinese companies." L-R: Akira Minamikawa, Research Director of Technology Research at IHS Markit; Atsuyoshi Koike, president at Western Digital Japan; Terushi Shimizu, representative director and president at Sony Semiconductor Solutions Talent key to bolstering competitiveness of Japan’s semiconductor industryMinamikawa of IHS Markit didn’t mince words in describing the talent shortage in the Japanese semiconductor industry as “grave,” saying that “the workforce challenge is not endemic to the electronics industry as evidence grows that the number of people obtaining doctorates in Japan is falling and the educational level of the Japanese population as a whole is in decline.”Three years ago, Shimizu interviewed professors on Kyushu island for insights into Japan’s talent shortfall. He came away feeling that “Japanese semiconductor companies were not sufficiently communicating the industry's talent and innovation needs to professors. To help professors and students better grasp the appeal and potential of the industry, we have started to send frontline engineers to universities to educate students and instructors about their work and careers. Expecting corporate HR departments to alone solve the talent shortage won’t work.”"In Japan, if you advance to a doctoral course, you will have a hard time getting a job, which is a strange situation,” Koike said. “Companies and universities need to work together more closely to better understand how to attract and hire doctoral graduates."Minamikawa said companies must have strong leaders with clear missions to attract the right talent, but Koike pointed to the drawbacks: "The image of a company with a strong leader seems to be cool, but it also has a downside because engineers stop thinking for themselves and wait for instructions from the top. I believe it is important for company leaders to have ongoing discussions at all organizational levels and lead the way in times of confusion."Shimizu agreed, citing his own company as an example."Thankfully, our company is very busy right now,” he said. “However, some employees are starting to request more time to think about how to improve the quality of their work. To maintain and strengthen our competitiveness and continue business growth, I believe it is important to cultivate an environment that encourages each employee to take more time to think for themselves."Motoaki Ito is the CEO of Enlight, Inc. and a reporter for SEMI.

As a top semiconductor manufacturing hub, Korea is poised to lead the world in fab construction spending in 2019 and 2020, accounting for 27 percent of the total market. Little wonder that Korea’s prowess in the semiconductor industry has meant steady membership growth for SEMI Korea, with HD Cho, president of SEMI Korea, putting the average annual jump at about 7 percent.But HD Cho’s focus as he returned to COEX in Seoul, home to SEMICON Korea, in late August was not on membership growth over the years but the future. Cho hosted about 400 SEMI members gathered at SEMI Korea Members Day for insights into the state of the world economy, semiconductor industry outlooks, and perspectives on how South Korean and European microelectronics companies can form stronger ties. Setting the stage with look at macroeconomics, Byung-yeon Kim, team manager of NH Investment and Securities, predicted that, as the global economy continues to falter, 25 of the 58 major countries this year will cut interest rates in a bid to boost prospects for growth. Historically, the global composite leading indicator (CLI), a bellwether for turning points in the economy, has rebounded after 20 months of decline, he said. While the CLI downtrend is now past the 20-month mark, Kim struck a bullish note, predicting that the global economy will bounce back before long.Soo-kyoum Kim, vice president at IDC, referring to the semiconductor industry’s own soft patch, said that total revenue is expected to drop from $475 billion in 2018 to $440 billion this year but should rebound to a new high of $500 billion in 2023. The memory market will be especially hard-hit, dropping more than 29 percent in 2019 and another 14 percent next year before bottoming and then staging a recovery in the second half of 2020. The strength of the rebound will hinge on server market demand, he added.Next year will also see rebounds in semiconductor equipment and materials revenue, with growth of 12 percent and 3 percent, respectively, said Clark Tseng, director of Industry Research and Statistics at SEMI. The increases will follow a 2019 equipment market drop of 18 percent to $53 billion from the previous year while materials this year is expected to remain flat at $52 billion. The semiconductor industry will expand at a modest 2.4 percent this year, jumping to 7.6 percent in 2020, Tseng reported, citing the average growth rate based on data from Gartner, WSTC, IC Insights, VLSI Research and other industry analyst firms. Despite current weak market demand and the ongoing trade war, the long-term outlook for the semiconductor industry remains upbeat, he added.In Europe, semiconductor industry growth continues on the strength of the region’s high strategic importance in the global electronics supply chain, said Laith Altimime, president of SEMI Europe. Fab construction spending in Europe continued to grow in 2018, reaching $300 million, and is expected to hit $1.2 billion in 2019 and $1.6 billion in 2020, with equipment, parts and components driving the surges.To help build stronger ties between European and Korean chip industries, Altimime introduced the SEMI Korea members to SEMI Europe business platforms including SEMICON Europe, the 3D System Summit, ISS Europe, and the MEMS Imaging Sensor Summit. He also encouraged the formation of more business partnerships between companies in the two regions by familiarizing SEMI Korea members with European players in areas such as foundry, MEMS, sensors and wafer manufacturing.And it will be MEMS and sensors that help drive the 4th Industrial Revolution, said Sung-hyuk Kim, a team leader at LG Electronics' Sensor Solution Research Institute. In his presentation Architecting Sensor Solutions for the Next Revolution, he noted that sensors are finding their way into devices where they have never been used before. In household refrigerators, gas sensors help deodorize the inside while distance sensors detect the approach of people. Air conditioners equipped with a camera sensor can pinpoint the location of humans and steer the airflow in their direction. Of course, all these smarts will come in form of data-devouring artificial intelligence (AI), and that data will be generated in massive amounts by MEMS and sensors – placing them at the epicenter of the 4th Industrial Revolution.Jaegwan Shim is a marketing specialist at SEMI Korea.

In the long unfolding arc of technology innovation, artificial intelligence (AI) looms immense. In its quest to mimic human behavior, the technology touches energy, agriculture, manufacturing, logistics, healthcare, construction, transportation and nearly every other imaginable industry – a defining role that promises to fast track the fourth Industrial Revolution. And if the industry oracles have it right, AI growth will be nothing shy of explosive.“The gains these days are not incremental,” said Ajit Manocha, SEMI president and CEO, said to a gathering in July of the Chinese American Semiconductor Professional Association (CASPA) for its Summer Symposium at SEMI’s headquarters in Milpitas. “They are hockey stick – exponential – with AI semiconductors growing in market size from $4 billion this year to $70 billion in 2025.”Manocha left little doubt that AI is remaking the semiconductor industry and, in the process, the world at large. Internet of Things (IoT) and 4G/5G, both key AI enablers, will account for more than 75 percent of device connections by 2025.“Today, 30 billion devices worldwide are connected,” Manocha said, citing an Applied Materials prediction that the number of connected devices globally will grow to between 500 billion and 1 trillion by 2030. Those devices will generate stunning amounts of data collected, interpreted and used to reason, solve problems, learn and plan, leading to the holy grail of autonomous machine behavior.To process this colossal amount of data central to the promise of AI, the industry must break through the limits of a key technology: memory. Memory a Critical AI BottleneckThe challenge for memory starts with performance. Historically, every decade gains in compute performance have outpaced improvements in memory speed by 100 times, and over the past 20 years that gap has grown, said Steven Woo, a fellow and distinguished inventor at Rambus, presenting at the symposium. The upshot is that memory has bottlenecked compute and, in turn, AI performance. The industry has responded with new ways to implement memory systems on AI chips. Each is suited to unique performance requirements and, of course, comes with trade-offs. Among the frontrunners: On-chip memory delivers the highest bandwidth and power efficiency but is limited in capacity. HBM (High Bandwidth Memory) offers both very high memory bandwidth and density. GDDR balances trade-offs among bandwidth, power efficiency, cost and reliability. Since 2012, AI training capability has grown 300,000 times, besting Moore’s law by 25,000 times in doubling every 3.5 months, a blistering pace compared to the 18-month doubling cycle of Moore’s law, Woo said. The staggering improvements have been driven by parallel computing capacity and new application-specific silicon like Google’s Tensor Processing Unit (TPU).These specialized silicon architectures and parallel engines are key to sustaining future gains in compute performance and combatting the slowing of Moore’s Law and the end of power scaling, Woo said. By rethinking the way processors are architected for certain markets, chipmakers can develop dedicated hardware capable of operating with 100 to 1,000 times greater energy efficiency than general purpose processors to overcome another big limiter to scaling compute performance – power.For its part, the memory industry can improve performance by signaling at higher data rates and using stacked architectures like HBM for greater power efficiency and performance, and by bringing compute closer to the data.Memory scaling for AIA key challenge is scaling memory for AI. Demand for better voice, gesture and facial recognition experiences and more immersive virtual reality and augmented reality interactions is tremendous, said Bill En, senior director at AMD, speaking at the symposium. These capabilities require more processing power across both high-performance computing (HPC) for big data analytics and machine learning as it relies on AI and machine intelligence to generate meaningful insights. Emerging machine learning applications include classification and security, medicine, advanced driver assistance, human-aided design, real-time analytics and industrial automation. And with 75 billion IoT-connected devices – all generating data – expected by 2025, there will be no shortage of data to analyze, En said. The wings alone of a new Airbus A380-1000 feature some 10,000 sensors.Mountains of this data are stored in massive data centers on magnetic hard drives, then transferred to DRAM before moving to SRAM within the CPU for the handoff to the compute hardware for analysis.With data growing at an exponential clip, the question is how to make sure all other memory systems can handle the flood of data. AMD’s answer is a chiplet architecture featuring eight smaller chips around the edge that drive the compute and a large chip in the center that doubles the IO interface and memory capability to in turn double chip bandwidth.AMD has also moved from a legacy GDDR5 memory chip configuration to HBM to bring memory bandwidth closer to the GPU for more efficient processing of AI applications. The HBM provides much higher bandwidth while reducing power consumption. Compared to DRAM, AMD’s HBM delivers a much faster data rate and far greater memory density, En said.Over the next decade, look for more performance improvements from multi-chip architectures, innovations in memory technology and integration, aggressive 3D stacking and streamlined system-level interconnects, he said. The industry will also continue to drive performance gains in devices, compute density and power through technology scaling.Michael Hall is a global marketing communications manager at SEMI.
