SanDisk and Toshiba announce their joint-venture has created world's first 48-layer 3D-stacked NAND flash memory. Called BiCS (short for bit cost scalable), this is a 2-bit-per-cell chip that offers a storage density of 128 gigabit (16GB). Sample shipments start today and mass production is expected to kick off in the first half of 2016 at the new Fab2 at Yokkaichi Operations.

For comparison, Samsung started mass production of 32-layer NAND last year. They are already achieving a storage density of 128Gb (16GB) but do so by using 3-bit-per-cell memory, which is starting to get a bad rep due to data retention issues.
SanDisk Corporation (NASDAQ:SNDK), a global leader in flash storage solutions, today announced that it has successfully developed its 48 layer second generation 3D NAND, also referred to as BiCS2. Pilot production will commence as planned in the second half of 2015 in the Yokkaichi joint venture facility, with meaningful commercial production targeted for 2016.

“We are very pleased to announce our second generation 3D NAND, which is a 48 layer architecture developed with our partner Toshiba,” said Dr. Siva Sivaram, executive vice president, memory technology, SanDisk. “We utilized our first generation 3D NAND technology as a learning vehicle, enabling us to develop our commercial second generation 3D NAND, which we believe will deliver compelling storage solutions for our customers.”

SanDisk plans to use the second generation 3D NAND technology across a broad range of solutions, from removable products to enterprise SSDs.
