SanDisk Announces 15nm NAND - Volume Production to Start 2H 2014

By Chris Ramseyer on Apr 24, 2014 at 12:35 am CDT

SanDisk today announced new 1Z, 15nm NAND flash in a press release (see below). This is an aggressive step for SanDisk since we're just starting to hear about upcoming products with new 1Y (19nm, 19mm x 19.5mm die)flash on consumer SSD products. The move from 1Y to 1Z should produce significantly more die per wafer reducing the cost of flash and thus end products.

In the press release, SanDisk states 1Z will scale a large product segment, from portable flash products to enterprise SSDs. This will not happen over night but it's a clear indication that SanDisk is able to shrink the lithography one more time until moving to 3D or stacked NAND.

Press Release:

MILPITAS, Calif., April 22, 2014 -SanDisk Corporation (NASDAQ: SNDK), a global leader in flash storage solutions, today announced the availability of its 1Z-nanometer (nm) technology, the most advanced NAND flash process node in the world. The 15nm technology will ramp on both two bits-per-cell (X2) and three bits-per-cell (X3) NAND flash memory architectures with production ramp to begin in the second half of 2014.

"We are thrilled to continue our technology leadership with the industry's most advanced flash memory process node, enabling us to deliver the world's smallest and most cost effective 128 gigabit chips,"� said Dr. Siva Sivaram, senior vice president, memory technology, SanDisk. "We are delighted that these new chips will allow us to further differentiate and expand our portfolio of NAND flash solutions."�

The 15nm technology uses many advanced process innovations and cell-design solutions to scale the chips along both axes. SanDisk's All-Bit-Line (ABL) architecture, which contains proprietary programming algorithms and multi-level data storage management schemes, has been implemented in the 1Z technology to deliver NAND flash solutions with no sacrifice in memory performance or reliability. SanDisk's 1Z technology will be utilized across its broad range of solutions, from removable cards to enterprise SSDs.
