Toshiba develops world’s first 256Gb, 48-layer BiCS FLASH
Toshiba America Electronic Components, Inc. (TAEC) today unveiled the new generation of BiCS FLASH, a three-dimensional (3D) stacked cell structure flash memory. The new device is the world’s first 256-gigabit (Gb4) (32 gigabyte) 48-layer BiCS FLASH device and also deploys industry-leading 3-bit-per-cell TLC (triple-level cell) technology. Sample shipments will start in September.
BiCS FLASH is based on a leading-edge 48-layer stacking process that surpasses the capacity of mainstream two dimensional NAND flash memory, while enhancing write/erase reliability endurance and boosting write speeds. The new 256Gb device is suited for diverse applications, including consumer SSDs, smartphones, tablets, memory cards, and enterprise SSDs for data centers.
Since announcing the prototype BiCS FLASH technology in June 2007, Toshiba has continued development towards optimization for mass production. To meet further growth in the flash memory market in 2016 and beyond, Toshiba is proactively promoting migration to BiCS FLASH by rolling out a product portfolio that emphasizes large capacity applications, such as SSDs.
“From day one, Toshiba’s strategy has been to extend our floating gate technology, which features the world’s smallest 15nm 128Gb die ,” noted Scott Nelson, senior vice president of TAEC’s Memory Business Unit. “Our announcement of BiCS FLASH, the industry’s first 48-layer 3D technology, is very significant in that we are enabling a competitive, smooth migration to 3D flash memory – to support the storage market’s demand for ever-increasing densities.”
Toshiba has a long-standing commitment to flash memory, and is currently readying for mass production of BiCS FLASH in the new Fab2 at Yokkaichi Operations, its production site for NAND flash memories. Fab2 will be completed in the first half of 2016.
