Sorting Out Next-Gen Memory

In the data center and related environments, high-end systems are struggling to keep pace with the growing demands in data processing. There are several bottlenecks in these systems, but one segment that continues to receive an inordinate amount of attention, if not part of the blame, is the memory and storage hierarchy. [getkc id="92" kc_name="SRAM"], the first tier of this hierarchy, is... » read more

How To Make 3D NAND

In 2013, Samsung reached a major milestone in the IC industry by shipping the world’s first 3D NAND device. Now, after some delays and uncertainty, Intel, Micron, SK Hynix and the SanDisk/Toshiba duo are finally ramping up or sampling 3D NAND. 3D NAND is the long-awaited successor to today’s planar or 2D NAND, which is used in memory cards, solid-state storage drives (SSDs), USB flash dr... » 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

3D NAND Market Heats Up

After some delays and uncertainty in past years, the 3D NAND market is finally heating up. In 2013 and 2014, Samsung was the only vendor participating in the 3D NAND market. Most other suppliers were supposed to ship 3D NAND devices in volumes last year, but vendors pushed out their production dates for various business and technical reasons. Going into 2015, [getentity id="22865" e_nam... » read more

Has 3D NAND Fallen Flat?

Today’s planar NAND technology will hit the wall at 10nm, prompting the need for the next big thing in flash memory—3D NAND. In fact, 3D NAND may extend NAND flash memory for the next several years and enable new applications. And it will also drive a new wave of fabs and tool orders. But the transition won’t be as smooth as previous rollouts. 3D NAND is harder to manufacture than pr... » read more

NAND ATE Market Gets Testy

The NAND flash memory market is undergoing big changes. As planar NAND moves further down the 1xnm node regime, suppliers are ramping up devices with new cell structures, interfaces and other features. And on top of that, 3D NAND is beginning to appear in the market. The next-generation NAND devices will enable new applications in the mobile and enterprise markets, but the chips themselves p... » 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

NAND Enters Tough Cycle

By Mark LaPedus The NAND flash memory market is entering into a new and painful cycle, a period that will impact suppliers, OEMs and fab tool vendors alike. For some time, there has been an oversupply and depressed pricing in the NAND market. In mid-2011, Micron, Samsung, SK Hynix and Toshiba put on the brakes in their capital spending plans. And in recent months, NAND suppliers in total h... » 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
