storage capability, is expected later this year, with meaningful commercial volumes of BiCS3 due first half 2017, said Western Digital in a news release. BiCS3, developed with Toshiba, is based on 3-bits-per-cell technology with high aspect ratio semiconductor processing, said to deliver high capacity and performance cost effectively. BiCS3 initially will be deployed in 256-gigabit capacity and will scale up to half a terabit storage on a single chip, said Western Digital. Volume shipments of BiCS3 for the retail market are due in Q4, with OEM sampling to begin this quarter. Shipments of the company’s previous-generation 3D NAND technology, BiCS2, continue to be available to customers in retail and OEM, it said.
