Toshiba Memory and Western Digital have officially opened their new NAND flash memory factory, Fab 6, at Yokkaichi in Mie Prefecture, Japan. At the facility, the companies will produce 96-layer 3D NAND (BiCS4) memory. Mass production of BiCS4 memory started earlier this month already.

The plans for the new facility were announced in November 2016, and construction started in February last year. As with its predecessor, Fab 5, construction will take place in two stages. Completion of the first stage was scheduled for summer 2018 and is now completed. Stage two will be built depending on market demand, if there is more demand, the second stage will be build for additional production capacity.

Besides the expansion of production capacity, the companies have also built a new research and development center at the same location. Construction of the center was completed in March this year.

Production of 96-layer 3D NAND started earlier this month, before the official opening of Fab 6.
