Western Digital doubles 3D-NAND capacity
Western Digital introduced a 256Gbit 3D-NAND flash memory in July 2016 (see Western Digital claims first 64-layer 3D NAND memory). Like that chip the latest model uses 64-layers and three-bits-per-cell implemented in Toshiba’s BICS3 technology.
Western Digital is presenting a technical paper the high aspect ratio semiconductor processing that allows 3D-NAND at the International Solid State Circuits Conference (ISSCC) in San Francisco.
