Continuing its advancements into smaller manufacturing processes, Toshiba America Electronic Components, Inc.
(TAEC) announced this week that it has developed second generation 19 nanometer process technology that will be used in the mass production of 2-bit-per-cell 64-gigabit NAND memory chips.
Toshiba's already used
the technology the develop what it claims is the world's smallest 2-bit-per-cell 64Gb NAND memory chips, which measure a scant 94 square millimeters in size. That's a 25 percent reduction over previous technology
. Though small in size, the chips are capable of writing 25 megabytes of data per second, the world's fastest class in 2-bit-per-cell territory, according to Toshiba.
The company said it's also working on 3-bit-per-cell chips using the same process technology and hopes to start mass producing those parts in the second quarter of this fiscal year. These new multi-level cell (MLC) parts will initially be introduced for smartphones and tablets via a special controller compatible with eMMC. Eventually Toshiba wants to extend the memory's application to notebook PCs, though it will first have to develop a compliant solid state drive (SSD) controller.
