Samsung hits high gear, rolls out densest flash chip

New 3-bit per cell, sub-20 nanometer flash designed for use in SSDs, as well as in smartphones and tablets

By , Computerworld |  Storage

The 128Gb NAND flash chips will be used by Samsung in its 128Gbyte (GB) memory cards. Samsung said it will now also increase its production volume of SSDs with densities over 500GB capacity for wider adoption of SSDs in computer systems, "while leading the transition of main storage drives in the notebook market from hard disk drives (HDDs) to SSDs."

Samsung currently uses TLC NAND in its SSD 840 Series drive, but that drive to date has used 64Gb flash chips.

Samsung started production of sub-20nm-class 64Gb MLC NAND flash memory in November last year. Over the past month, it has begun adding the new 128Gb NAND flash to its flash memory offerings. The new 128Gb chip also extends Samsung's 3-bit NAND memory line-up along with the 20nm-class 64Gb 3-bit NAND flash chip that Samsung introduced in 2010.
