Samsung producing 30nm 3-bit, DDR flash memory (MLC NAND)
Samsung said this morning that it has started mass production of 2 different kinds of 30nm (Nanometer) Multi-Lever Cell NAND memory, 3 times faster than actual NAND chips offering at peak a 133Mbps speed instead of the actual 40Mbps.
Samsung Electronics Co., Ltd., the world leader in advanced semiconductor technology solutions, announced today that it commenced the industry’s first volume production of 3-bit, multi-level-cell (MLC) NAND flash chips using 30-nanometer (nm)-class process technology at the end of November. 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 a few minutes ago) are expected to also contribute greatly to this trend.
