4-bit-per-cell flash by Spansion


Tuesday, January 23, 2007 Spansion Inc is pushing its four-bit-per-cell MirrorBit flash memory into production this quarter with densities ranging from 256Mbit to 2Gbit.

The first batch of MirrorBit Quad chips will use a 90nm process at Spansion's Fab 25 (Austin) and will be drop-in compatible with other industry-standard NAND products, the company said.

Later this year, Spansion will reveal plans for 65nm-based products. 

If MirrorBit gains traction, the 4-bit technology could challenge Intel Corp. in the market for high-density data-storage flash devices for third-generation wireless phones. Intel pioneered 2-bit/cell flash technology with its StrataFlash line, introduced in 1997.
