Samsung Aanounces industry?s first 30-nm-class, 3-bit MLC NAND Flash

Posted December 2, 2009 by admin in News

The chips will be used in NAND flash modules accompanied by exclusive Samsung 3-bit NAND controllers to initially produce eight gigabyte (GB) micro Secure Digital (microSD) cards.

“Introducing cost-efficient, 30nm-class 3-bit technology widens our NAND memory solution base to make NAND even more enticing for increasingly diverse market applications,” said Soo-In Cho, executive vice president and general manager of the Memory Division at Samsung Electronics. “Our 3-bit NAND memory will support the development of more cost-competitive, high-density consumer electronics storage solutions,” he added.

Three-bit MLC NAND increases the efficiency of NAND data storage by 50 percent over today’s pervasive 2-bit MLC NAND chips. Samsung’s new 30nm-class 3-bit MLC NAND will provide consumers with effective NAND-based storage that can be applied to USB flash drives in addition to a range of micro SD cards.

In 2005, Samsung introduced the first 50nm-class, 16Gb MLC NAND memory device, ushering in an era of unprecedented growth for flash memory beyond the high-performance SLC (single-level-cell) market. Mass production of 30nm 3-bit NAND is expected to significantly raise the portion of NAND flash memory production devoted to high densities (32Gb and above), designed to accommodate increased video usage.

Other NAND advancements, like the introduction of asynchronous double data rate MLC NAND memory (see separate release issued at 6:00 pm PT) are expected to also contribute greatly to this trend.
