Toshiba starts 15nm mass flash production this month.

Toshiba says it will start 15nm NAND flash production at the end of the month in Fab 5 at Yokkaichi.

Initial product will be 2bit-per-cell 128Gbit flash.

Toshiba says it has achieved the world’s smallest class chip size but doesn’t say what it is.

15nm chips have the same write speed as 19nm chips but boost the data transfer rate to 533 megabits a second -  1.3 times faster – by employing a high speed interface.

Toshiba is applying the 15nm process technology 3-bit-per-cell chips, and aims to start mass production in Q2.
