Toshiba launches 15nm memory process

Written by Nick Farrell

Flash will save everyone of us

Toshiba has launched of its 15nm process technology at least for 2-bit-per-cell 128 gigabit (16 gigabytes) NAND Flash memory. The technology will kill off second generation 19nm process technology and full production with the new technology next week at Toshiba's Fab 5 in Yokkaichi.

Chips based on the new processing technology will have better peripheral circuitry technology. They will have the write speed as chips formed with 19nm process technology, but boost the data transfer rate to 533 megabits per second which is 1.3 times faster, particularly if it is going downhill with the wind behind it.

In its press release, the company said it would develop controllers for embedded NAND flash memory in parallel and introduce 3-bit-per-cell products for smartphones and tablets, and will subsequently extend application to notebook PCs by developing a controller compliant with solid state drives.

It is not the only outfit using the technology SanDisk said it will release the technology as part of its 1Znm process node. The 15nm technology will ramp on both 2-bit-per-cell (X2) and 3-bit-per-cell (X3) NAND flash memory architectures, with production ramp to begin in the second half of 2014.

Siva Sivaram, senior vice president, memory technology, SanDisk said the technology will allow the company to deliver the world's smallest and most cost effective 128 gigabit chips. The 1Z technology will be utilized across a broad range of products, the company reveals, including memory cards and enterprise SSDs, he said.
