We just had the transition towards 25nm NANF flash, but 24 NAND flash is already arround the corner.

At the upcoming Flash Memory Summit, which is scheduled to open its gates later today in Santa Clara, California, SandForce is going to demonstrate a prototype SSD which uses 24nm MLC (multi-level cell) toggle NAND Flash chips manufactured by Toshiba.

These complement the control IC introduced by Toshiba in its 24nm toggle NAND Flash memory, which runs a special error checking and correction (ECC) algorithm on the chips without placing any burden on the host controller.

By using this technology, Toshiba claims that 24nm NAND allows for 1.9 times faster read speeds and 1.5 times faster write speeds, when compared with the current 32-nm generation devices.

According to the SandForce press release, Toshiba 24nm toggle Flash memory can operate up to 166 mega-transfers per second.
