Toshiba plans to build two new fabs in Japan, including one for NAND flash memory on the site of Iwate Toshiba Electronics Co., a Toshiba consolidated subsidiary, and adjacent to Toshiba's Yokkaichi Operations, where four NAND flash fabs are already in operation. One of the new fabs will initially make advanced generations of NAND flash memory and the other will provide capacity to meet Toshiba's future semiconductor requirements.
