SK hynix shows off 176-layer 4D NAND flash

SK hynix has announced that it has completed the development of the industry's most multilayered 512-gigabit triple-level cell (TLC) 4D NAND flash comprised of 176 layers. The company says it provided samples to controller companies last month so they could design products around it. Previously, SK hynix promoted its 4D technology using a 96-layer NAND flash product combining Charge Trap Flash with high-integrated Peri.
