Ah, the joys of healthy competition in the market. Last week 20nm NAND Flash was cutting edge and now it's so, well, uhm, last week. Both SanDisk and Toshiba have separately announced that they'll be offering retail 19nm NAND Flash memory later this year. Reading the press releases it appears to be the same tech, but we can't be certain of it, but both companies announced two bits per cell NAND Flash with three bits per cell coming at a later stage.

Ah, the joys of healthy competition in the market. Last week 20nm NAND Flash was cutting edge and now it's so, well, uhm, last week. Both SanDisk and Toshiba have separately announced that they'll be offering retail 19nm NAND Flash memory later this year. Reading the press releases it appears to be the same tech, but we can't be certain of it, but both companies announced two bits per cell NAND Flash with three bits per cell coming at a later stage.

Both SanDisk and Toshiba have announce 64Gbit chips, that's 8GB in more useful terms and it should mean that we'll be seeing cheaper flash memory cards towards the end of the year, especially at higher capacity. Toshiba is also promising 128GB stacked chips for Smartphones and tablets using Toggle DDR2 technology for improved performance. This is all great news for consumers, but there are concerns that these new die shrunk NAND Flash memory chips won't last as long as what we're used to, although SanDisk claims that there's no need to worry as its new memory chips are just as reliable as its old ones.

Both companies are sampling now with SanDisk saying second half and Toshiba third quarter for volume production. As to when the three bit per cell chips will arrive in the market isn't made clear by either company's press release, so we'll just have to wait and see. Despite a lot of concerns about the longevity of smaller NAND Flash memory chips, it seems like the 19-20nm parts aren't significantly different from the current 2xnm parts which is at least some good news.
