Toshiba Invests in Sub-25nm NAND Flash Chip Making Equipment

Paul Lilly

Toshiba said it is investing heavily in chip-making equipment that will enable the world's No. 2 NAND flash memory maker to produce microchips built on a sub-25nm manufacturing process.

The shrink to below 25nm will pave the way for higher capacities on smaller slices of silicon that are cheaper to produce, so it's a win all around. Toshiba's current product is stuck at 32nm and 43nm, and the company will spend $160 million this year in order to build a test production line for the smaller chips.

According to Japanese newspaper Nikkei Business Daily, Toshiba will soon begin churning out NAND chips with circuitry widths in the upper 20 nanometer range in the second half of this year. NAND chips with circuitry widths in the lower 20 nanometer range could begin as early as 2012.
