Prediction of SRAM Reliability Under Mechanical Stress Induced by Harsh Environments
By Fraunhofer IIS/EAS - 07 Nov, 2018 - Comments: 0

On the example of a 28nm SRAM array, this work presents a novel reliability study which takes into account the effect of externally applied mechanical stress in circuit simulations. This method is able to predict the bit failures caused by the stress via the piezoresistive effect. The stability of each single SRAM cell is simulated using static noise margin. Finally, the whole array’s behavio... » read more

Zeno Semi Expands On-Chip Memory
By Kevin Fogarty - 30 Oct, 2018 - Comments: 0

San Jose, Calif.-based startup Zeno Semiconductor is testing modifications and a smaller process node for the single-transistor 28nm SRAM chip it introduced in 2016, which could boost space for on-chip CPU memory by more than 2.5X, according to the co-founder and CEO of the company, Yuniarto Widjaja. The Zeno-1 transistor is built on standard CMOS processes, has a bi-stable bipolar transisto... » read more

Week In Review: Design, Low Power
By Jesse Allen - 28 Sep, 2018 - Comments: 0

Arm announced a new processor targeted at autonomous driving applications. The Cortex-A76AE is a superscalar, out-of-order processor that incorporates Split-Lock safety technology. Split-Lock allows CPU clusters in an a SoC to be configured either in ‘split mode’ for high performance, allowing two (or four) independent CPUs in the cluster to be used for diverse tasks and applications, or �... » read more

Hybrid Memory

Gary Bronner, senior vice president of Rambus Labs, talks about the future of DRAM scaling, why one type of memory won’t solve all needs, and what the pros and cons are of different memories. https://youtu.be/R0hhDx2Fb7Q » read more

Processing In Memory
By Ed Sperling - 05 Sep, 2018 - Comments: 1

Adding processing directly into memory is getting a serious look, particularly for applications where the volume of data is so large that moving it back and forth between various memories and processors requires too much energy and time. The idea of inserting processors into memory has cropped up intermittently over the past decade as a possible future direction, but it was dismissed as an e... » read more

Next-Gen Memory Ramping Up
By Mark LaPedus - 16 Aug, 2018 - Comments: 6

The next-generation memory market is heating up as vendors ramp a number of new technologies, but there are some challenges in bringing these products into the mainstream. For years, the industry has been working on a variety of memory technologies, including carbon nanotube RAM, FRAM, MRAM, phase-change memory and ReRAM. Some are shipping, while others are in R&D. Each memory type is di... » read more

AI Architectures Must Change
By Brian Bailey - 13 Aug, 2018 - Comments: 4

Using existing architectures for solving machine learning and artificial intelligence problems is becoming impractical. The total energy consumed by AI is rising significantly, and CPUs and GPUs increasingly are looking like the wrong tools for the job. Several roundtables have concluded the best opportunity for significant change happens when there is no legacy IP. Most designs have evolved... » read more

Embedded Flash Scaling Limits
By Mark LaPedus - 19 Jul, 2018 - Comments: 3

Embedded nonvolatile flash memory has played a key role in chips for years, but the technology is beginning to face some scaling and cost roadblocks and it’s not clear what comes next. Embedded flash is used in several markets, such as automotive, consumer and industrial. But the automotive sector appears to be the most concerned about the future of the technology. Typically, a car incorpo... » read more

ISO 26262 Statistics
By Ed Sperling - 02 Jul, 2018 - Comments: 0

Jorg Gosse, functional safety product manager at OneSpin Solutions, talks about the statistics behind the standards, what is considered good enough, and how those numbers vary across different standards. https://youtu.be/cNTFN3kQ-OM » read more

Etch Techniques for Next-Generation Storage-Class Memory
By Alex Yoon - 21 Jun, 2018 - Comments: 0

Chipmakers make abundant use of two very different functional classes of memory in their products. For operational use (main/primary memory) where speed is critical, DRAM and SRAM are employed, whereas for long-term storage, flash memory – in particular NAND – provides the high capacity at low cost needed. For both classes, efforts to improve speed, capacity, and power usage are ongoing. To... » read more
