Toshiba has announced it has started mass production of 24nm NAND flash memory, hot on the heels of Intel’s recent 25nm announcement.
Toshiba has announced it has started mass production of 24nm NAND flash memory, hot on the heels of Intel’s recent 25nm announcement.
24nm technology will shrink chip size even further. Toshiba has already applied the 24nm technology to 2bit-per-cell 64-gigabit chips, allowing them to offer up to 8GB of storage per chip. Toshiba has also equipped its 24nm NAND with Toggle DDR, which enhances data transfer speed.
Toshiba says it is planning to add 32-gigabit and 3bit-per-cell products fabricated with 24nm technology, though no date was specified.
Intel is planning to introduce 3bit-per-cell NAND flash memory built on a 25nm process to mass production later this year. Given Toshiba is just introducing 2bit-per-cell 24nm chips, this means Intel is ahead of the competition. Intel says 3bit-per-cell technology allows them to deliver the same capacity as 2bit-per-cell in a chip 20% smaller.
