Toshiba to Start Mass Production of 19nm NAND Flash Memory …

Toshiba Corporation and Toshiba America Electronic Components, Inc. (TAEC) has developed second generation 19nm process technology that it will apply to mass production of 2-bit-per-cell 64 gigabit NAND memory chips later this month.

Toshiba has used the new generation technology to develop the smallest 2-bit-per-cell 64 gigabit NAND memory chips, with an area of 94 square millimeters. Using a high speed writing method, the next generation chips can achieve a write speed of up to 25MB/s.

Toshiba is also developing 3-bit-per-cell chips by using this process technology and aims to start mass production in the second quarter of this fiscal year. The company will initially introduce 3-bit, MLC products for smartphones and tablets by developing a controller compatible with eMMC, and will subsequently extend application to notebook PCs by developing a controller compliant with SSD.

NAND flash memory is an component of a diverse line-up of consumer products, including memory cards, smartphones, tablets and notebook PCs, and is deployed in enterprise products, including SSD for data centers.
