According to Dr. Siva Sivaram, senior vice president of memory technology at SanDisk, “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.  We are delighted that these new chips will allow us to further differentiate and expand our portfolio of NAND flash solutions.”

The new 15nm technology features numerous advanced process innovations, and cell-designs that allow scaling of the chips along both axes.  SanDisk will be implementing its All-Bit-Line (ABL) architecture containing proprietary programming algorithms and multi-level storage management routines into the 1Z technology, which will create NAND flash products with no sacrifice in reliability or performance.

SanDisk intends to utilize the new 1Z process technology across its wide range of flash storage devices; from removable flash cards all the way up to enterprise SSDs.  The SanDisk press release announcing the new 15nm process technology can be viewed in its entirety here.
