3D QLC
Kioxia and Western Digital formally introduced their 8th Generation BiCS 3D NAND memory with 218 active layers. The new storage device offers a 1Tb capacity in 3D TLC mode and features 3200 MT/s data transfer speed, a combination that will enable SSD makers to build high-performance, high-capacity drives. To enable such an extreme interface speed, the companies adopted an architecture akin to YMTC's Xtacking. The 218-layer BiCS 3D NAND device jointly developed by Kioxia and Western Digital supports triple-level cell (TLC) and quad-level cell (QLC) configurations to maximize storage density and expand addressable applications. The companies said that the new device embraces their new 'lateral shrink technology to increase bit density by over 50' without elaborating. Considering that the flash memory IC increased the number...
