Is There A Limit To The Number of Layers In 3D-NAND?


Memory vendors are racing to add more layers to 3D NAND, a competitive market driven by the explosion in data and the need for higher-capacity solid state drives and faster access time. Micron already is filling orders for 232-layer NAND, and not to be outdone, SK Hynix announced that it will begin volume manufacturing 238-layer 512Gb triple level cell (TLC) 4D NAND in the first half of next... » 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
