What Is DRAM’s Future?


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


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


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


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

MRAM Process Development And Production Briefing


By Dr. Meng Zhu, Dr. Roman Sappey, and Jeff Barnum MRAM (Magnetoresistive Random-Access Memory) is a type of non-volatile memory (NVM) that utilizes magnetic states to store information. The basic structure of MRAM is a magnetic-tunnel junction (MTJ), which consists of two ferromagnetic (FM) layers separated by an insulating tunnel barrier (Fig.1). When the magnetizations of the two magnetic... » read more

A New Breed Of Engineer


The industry loves to move in straight lines. Each generation of silicon is more-or-less a linear extrapolation of what came before. There are many reasons for this – products continue to evolve within the industry, adding new or higher performance interfaces, risk levels are lower when the minimum amount is changed for any chip spin, existing software is more likely to run with only minor mo... » read more

An Increasingly Complicated Relationship With Memory


The relationship between a processor and its memory used to be quite simple, but in modern SoCs there are multiple heterogeneous processors and accelerators, each needing a different means of accessing memory for maximum efficiency. Compromises are being made in order to preserve the unified programming model of the past, but the pressures are increasing for some fundamental changes. It does... » read more

2020 IC Outlook: Uncertainty


After a downturn in 2019, the semiconductor and equipment industries looked promising at the start of 2020. In 2019, the downturn was primarily due to the memory markets, namely DRAM and NAND. Both DRAM and NAND saw lackluster demand and falling prices last year. At the start of 2020, though, the memory markets were beginning to recover. Unlike memory, the logic and foundry markets were s... » read more

Changes In AI SoCs


Kurt Shuler, vice president of marketing at ArterisIP, talks about the tradeoffs in AI SoCs, which range from power and performance to flexibility, depending on whether processing elements are highly specific or more general, and the need for more modeling of both hardware and software together. » read more

Logic Chip, Heal Thyself


If a single fault can kill a logic chip, that doesn’t bode well for longevity of complex multi-chip systems. Obsolescence in chips is not just an industry ploy to sell more chips. It is a fact of physics that chips don’t last more than a few years, especially if overheated, and hit with higher voltage than it can stand. The testing industry does a great job finding defects during manufac... » read more
