Next-generation NAND flash memory coming soon from Toshiba
Toshiba has used the new generation technology to develop the world’s smallest 2-bit–per-cell 64 Gigabit NAND memory chips, with an area of only 94 square millimetres. Using a unique high-speed writing method, the next generation chips can achieve a write speed of up to 25 Mbytes/sec, claimed as the fastest-available for 2-bit-per-cell chips.
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, 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).
