TOKYO -- Toshiba will ramp up production of next-generation memory chips while paring back its hard drive business and selling other chipmaking operations, aiming for a speedy return to profitability after expensive post-scandal restructuring.
The Japanese company plans by March to begin mass production of 3-D NAND flash memory, in which memory cells are stacked vertically to boost capacity. New production lines being built at fabrication facilities in Yokkaichi in Mie Prefecture are partially complete. Lithography and other equipment will be brought in gradually. Construction will be complete by June.
