Toshiba and SanDisk are the joint partners in the NAND fab venture.The initial manufacturing process will be the leading-edge 20-nm generation, with subsequent generations to follow.

The fab building will be constructed in two phases, with the pace of investment reflecting market trends.

Yokkaichi Operations currently has four NAND flash memory fabs. Toshiba and SanDisk are currently ramping into the unused clean room space in Fab 4, and expect to reach full capacity of Fab 4 by the start of production in Fab 5.

 

Construction work is scheduled for completion in the spring of 2011.
