DDR5: The Next-Generation Technology For High Performance Computing
By Synopsys - 13 May, 2020 - Comments: 1

The rapid growth in real-time data requirements for cloud services, IoT, high-performance servers and workstations, hyperscale data centers and big data has increased pressure on memory suppliers to improve memory density and speed. This pressure has resulted in a need for new memory technology that goes beyond the current DDR4 limit of 16 Gb single die capacity and speed of 3200MT/s. Click ... » read more

Taking A Pulse On The IC Biz
By Mark LaPedus - 16 Apr, 2020 - Comments: 0

It’s been a difficult period for the semiconductor industry. The coronavirus outbreak has put a damper on what was supposed to be a strong year in the semiconductor industry in 2020. Many are holding out hopes for a rebound in the second half of the year. That’s still a big unknown. The forecasts are gloomy. For example, VLSI Research has three different scenarios for the semiconduc... » read more

Power Becomes Bigger Concern For Embedded Processors
By Ann Mutschler - 15 Apr, 2020 - Comments: 0

Power is emerging as the dominant concern for embedded processors even in applications where performance is billed as the top design criteria. This is happening regardless of the end application or the process node. In some high-performance applications, power density and thermal dissipation can limit how fast a processor can run. This is compounded by concerns about cyber and physical secur... » read more

NVM Reliability Challenges And Tradeoffs
By Bryon Moyer - 13 Apr, 2020 - Comments: 0

This second of two parts looks at different memories and possible solutions. Part one can be found here. While various NVM technologies, such as PCRAM, MRAM, ReRAM and NRAM share similar high-level traits, their physical renderings are quite different. That provides each with its own set of challenges and solutions. PCRAM has had a fraught history. Initially released by Samsung, Micron, a... » read more

2.5D Architecture Answers AI Training’s Call for “All of the Above”
By Frank Ferro - 09 Apr, 2020 - Comments: 0

The impact of AI/ML grows daily impacting every industry and touching the lives of everyone. In marketing, healthcare, retail, transportation, manufacturing and more, AI/ML is a catalyst for great change. This rapid advance is powerfully illustrated by the growth in AI/ML training capabilities which have since 2012 grown by a factor of 10X every year. Today, AI/ML neural network training mod... » read more

What Is DRAM’s Future?
By Bryon Moyer - 09 Apr, 2020 - Comments: 0

Memory — and DRAM in particular — has moved into the spotlight as it finds itself in the critical path to greater system performance. This isn't the first time DRAM has been the center of attention involving performance. The problem is that not everything progresses at the same rate, creating serial bottlenecks in everything from processor performance to transistor design, and even the t... » read more

Auto Outlook: Down But Not Out
By Mark LaPedus - 19 Mar, 2020 - Comments: 0

For years, automotive has been an engine of growth in the semiconductor industry, although the market is expected to decline in 2020. Several types of chips are used in automobiles, such as analog, memory, microcontrollers, processors and RF. But the automotive IC business still represents a small percentage of the overall semiconductor market. It pales in comparison to the smartphone chip m... » read more

HBM Issues In AI Systems
By Brian Bailey - 16 Mar, 2020 - Comments: 0

All systems face limitations, and as one limitation is removed, another is revealed that had remained hidden. It is highly likely that this game of Whac-A-Mole will play out in AI systems that employ high-bandwidth memory (HBM). Most systems are limited by memory bandwidth. Compute systems in general have maintained an increase in memory interface performance that barely matches the gains in... » read more

Testing Embedded MRAM IP For SoCs
By Synopsys - 11 Mar, 2020 - Comments: 0

The challenges of embedded memory test and repair are well known, including maximizing fault coverage to prevent test escapes and using spare elements to maximize manufacturing yield. With the surge in availability of promising non-volatile memory architectures to augment and potentially replace traditional volatile memories, a new set of SoC level memory test and repair challenges are emerging... » read more
