Toshiba Corp. and Toshiba America Electronic Components Inc. have revealed that they have developed what they describe as a second generation 19nm process technology that it will apply to mass production of 2bit-per-cell 64Gb NAND memory chips later this month. The chips feature an area of 94mm2. Toshiba said the chips can achieve a write speed of up to 25MB/s, which it boasts as the world's fastest class in 2bit-per-cell chips.

Toshiba is also developing 3bit-per-cell chips by using this process technology and aims to start mass production in Q2 of this fiscal year. The company will initially introduce 3bit, multi-level-cell 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 solid state drives (SSD).

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