CXL: The Future Of Memory Interconnect?


Momentum for sharing memory resources between processor cores is growing inside of data centers, where the explosion in data is driving the need to be able to scale memory up and down in a way that roughly mirrors how processors are used today. A year after the CXL Consortium and JEDEC signed a memorandum of understanding (MOU) to formalize collaboration between the two organizations, suppor... » read more

MRAM Getting More Attention At Smallest Nodes


Magneto-resistive RAM (MRAM) appears to be gaining traction at the most advanced nodes, in part because of recent improvements in the memory itself and in part because new markets require solutions for which MRAM may be uniquely qualified. There are still plenty of skeptics when it comes to MRAM, and lots of potential competitors. That has limited MRAM to a niche role over the past couple de... » read more

A Novel Complementary Architecture of One-time-programmable Memory and Its Applications as Physical Unclonable Function (PUF) and One-time Password


Abstract "For the first time, we proposed a 2T complementary architecture of one-time-programmable memory (OTP) in a foundry logic CMOS chip. It was then used to realize the PUF (Physical unclonable function), and the combination with the AI technology to provide a one-time password capability. At first, an OTP was developed based on a novel 2T CMOS unit cell. The experimental results show t... » read more

CodaCache: Helping to Break the Memory Wall


As artificial intelligence (AI) and autonomous vehicle systems have grown in complexity, system performance needs have begun to conflict with latency and power consumption requirements. This dilemma is forcing semiconductor engineers to re-architect their system-on-chip (SoC) designs to provide more scalable levels of performance, flexibility, efficiency, and integration. From the edge to data ... » read more

Why DRAM Won’t Go Away


Semiconductor Engineering sat down to talk about DRAM's future with Frank Ferro, senior director of product management at Rambus; Marc Greenberg, group director for product marketing at Cadence; Graham Allan, senior product marketing manager for DDR PHYs at Synopsys; and Tien Shiah, senior manager for memory marketing at Samsung Electronics. What follows are excerpts of that conversation. Part ... » read more

Using Memory Differently


Chip architects are beginning to rewrite the rules on how to choose, configure and use different types of memory, particularly for chips with AI and some advanced SoCs. Chipmakers now have a number of options and tradeoffs to consider when choosing memories, based on factors such as the application and the characteristics of the memory workload, because different memory types work better tha... » read more
