Toshiba on Wednesday introduced its first BiCS 3D TLC NAND flash chips with 512 GB and 1 TB capacities. . The new ICs stack 8 or 16 3D NAND devices using through silicon vias (TSVs) and are currently among the highest capacity non-volatile memory stacks available in the industry. Commercial products powered by the 512 GB and 1 TB packages are expected to hit the market in 2018, with an initial market focus on high-end enterprise SSDs Stacking NAND devices to build high capacity flash memory ICs has been used for years to maximize the capacities and performance of SSDs and other solid state storage devices. In many cases, NAND makers use wire-bonding technique to stack multiple memory devices, but it makes packages larger and...
