leadership in NAND flash and solid execution to our technology roadmap,” said Dr. Siva Sivaram, executive vice president of memory
technology at Western Digital. “BiCS4 will be available in 3-bits-per-cell and 4-bits-per-cell architectures, and it contains
technology and manufacturing innovations to provide the highest 3D NAND storage capacity, performance and reliability at an
attractive cost for our customers. Western Digital’s 3D NAND portfolio is designed to address the full range of end markets
spanning consumer, mobile, computing and data center.”
The company also highlighted strong ongoing operations at its joint venture manufacturing facilities in Japan. In particular,
the company reiterated its expectation that in calendar year 2017, the output mix of its 64-layer 3D NAND technology, BiCS3, will
comprise more than 75 percent of its overall 3D NAND bit supply. The company now believes that, along with its partner Toshiba
Corporation, the combined 64-layer 3D NAND bit output of the joint ventures in calendar year 2017 will be higher than any other
industry supplier in calendar year 2017.
