Samsung Now Producing 20nm-class, 64-gigabit 3-bit NAND Flash Memory
(Nanowerk News) Samsung Electronics Co., Ltd., the world leader in advanced memory technology, announced today the industry's first production of a 3-bit-cell (3bit), 64 gigabit (Gb) NAND flash using 20 nanometer (nm)-class* process technology. The highly advanced new chip can be used in high-density flash solutions such as USB flash drives (UFDs) and Secure Digital (SD) memory cards.
"Samsung has repeatedly provided the market with leading-edge NAND flash solutions, including the introduction of 30nm-class*, 32Gb 3-bit NAND flash last November," said Seijin Kim, vice president, Flash Memory Planning/Enabling, Samsung Electronics. "By now entering into full production of 20nm-class 64Gb 3-bit devices, we expect to accelerate adoption of our high-performance NAND solutions that use Toggle DDR technology, for applications that also require high-density NAND."
The availability of storage density as high as eight gigabytes (64Gb) in a single chip will trigger widespread acceptance of Toggle DDR-based high-performance flash in UFDs and SD cards, as well as smart phones and SSDs, while replacing previous four gigabyte (32Gb) devices in the market.
Samsung's 20nm-class, 64Gb 3-bit NAND has a 60 percent higher productivity level than 30nm-class, 32Gb 3-bit NAND. The device also offers improved performance by applying Toggle DDR (Double Data Rate) 1.0 specifications, compared to those of SDR (Single Data Rate) based 30nm-class NAND chips.
Following the production of 20nm-class 32Gb MLC NAND in April, Samsung expands its product offerings at the leading-edge 20nm-class process node with the introduction of the 20nm-class 64Gb 3-bit NAND.
*) 20nm-class means a process technology node somewhere between 20 and 29 nanometers and 30nm-class means a process technology node somewhere between 30 and 39 nanometers.
