Four Foundries Back MRAM


Four major foundries plan to offer MRAM as an embedded memory solution by this year or next, setting the stage for what finally could prove to be a game-changer for this next-generation memory technology. GlobalFoundries, Samsung, TSMC and UMC plan to start offering spin-transfer torque magnetoresistive RAM (ST-MRAM or STT-MRAM) as an alternative or a replacement to NOR flash, possibly start... » read more

China Unveils Memory Plans


Backed by billions of dollars in government funding, China in 2014 launched a major initiative to advance its domestic semiconductor, IC-packaging and other electronic sectors. So far, though, the results are mixed. China is making progress in IC-packaging, but the nation’s efforts to advance its domestic logic and memory sectors are still a work in progress. In fact, China has yet to achi... » read more

What’s Next For NAND?


NAND flash memory is a key enabler in today’s systems, but it’s a difficult business. NAND suppliers require deep pockets and strong technology to survive in the competitive landscape. And going forward, vendors face new challenges on several fronts. On one front, for example, the overall NAND market is currently in the doldrums, amid soft product prices and a mild capacity glut. Demand ... » read more

Memory Hierarchy Shakeup


It’s no secret that today’s memory chips and storage devices are struggling to keep up with the growing demands in data processing. To solve the problem, chipmakers have been working on several next-generation memory types. But most technologies have been delayed or fallen short of their promises. But after numerous delays, a new wave of next-generation, nonvolatile memories are finally ... » read more

The Bumpy Road To 3D NAND


The NAND flash memory market is dynamic, but it’s also sometimes predictable. Suppliers tend to roll out identical NAND flash chips and then scale them to smaller geometries. And NAND chip prices rise and fall, depending on the supply/demand equation at a given point. Going forward, though, the NAND market is expected to become less predictable, if not chaotic, amid a new and major technol... » read more

What’s After 3D NAND?


By Mark LaPedus Planar NAND flash memory is on its last scaling legs, with 3D NAND set to become the successor to the ubiquitous 2D technology. Samsung Electronics, for one, already has begun shipping the industry’s first 3D NAND device, a 24-level, 128-gigabit chip. In addition, Micron and SK Hynix shortly will ship their respective 3D NAND devices. But the Toshiba-SanDisk duo are the lo... » read more

Universal Memories Fall Back To Earth


By Mark LaPedus Ten years ago, Intel Corp. declared that flash memory would stop scaling at 65nm, prompting the need for a new replacement technology. Thinking the end was near for flash, a number of companies began to develop various next-generation memory types, such as 3D chips, FeRAM, MRAM, phase-change memory (PCM), and ReRAM. Many of these technologies were originally billed as “uni... » read more

What’s After NAND Flash?


By Mark LaPedus For years, many have predicted the end of flash memory scaling, particularly NAND, but the technology continues to defy the odds as it moves down the process curve. Still, there are signs that the floating gate structure in today’s flash memory is on its last legs. The floating gate is seeing an undesirable reduction in the control gate to capacitive coupling ratio. And ... » read more
