Western Digital Corp. (NASDAQ: WDC) today announced successful
development of its second-generation, four-bits-per-cell
architecture for 3D NAND. Implemented for the company’s 96-layer
BiCS4 device, the QLC technology delivers the industry’s highest 3D
NAND storage capacity of 1.33 terabits (Tb) in a single chip. BiCS4
was developed at the joint venture flash manufacturing facility in
Yokkaichi, Japan with our partner Toshiba Memory Corporation. It is
sampling now and volume shipments are expected to commence this
calendar year beginning with consumer products marketed under the
SanDisk brand. The company expects to deploy BiCS4 in a wide

“Leveraging Western Digital’s silicon processing, device
engineering and system integration capabilities, the QLC technology
allows 16 distinct levels to be sensed and utilized for storing
data,” said Dr. Siva Sivaram, executive vice president, Silicon
Technology and Manufacturing at Western Digital. “BiCS4 QLC is our
second generation four-bits-per-cell device, and it builds on the
learnings from our QLC implementation in 64-layer BiCS3. With the
best intrinsic cost structure of any NAND product, BiCS4
underscores our strengths in developing flash innovations that
allow our customers’ data to thrive across retail, mobile,
embedded, client and enterprise environments. We expect the
four-bits-per-cell technology will find mainstream use in all these
applications.”
