The New Fab 2 facility will support the conversion of the companies' 2D NAND capacity to 3D flash memory, allowing realization of solutions offering higher densities and better device performance. Construction of New Fab 2 began in September 2014. Following partial completion of the facility in October 2015, Toshiba and SanDisk (acquired in May 2016 by Western Digital Technologies Inc., a wholly owned subsidiary of Western Digital Corporation) worked together to implement leading-edge manufacturing capabilities for mass production of 3D flash memory, and first-phase production started in March of this year. The parties intend to further invest to expand production capacity over time, depending on market conditions. In addition, Yokkaichi operations will leverage the site-wide integrated production system, which employs big data processing to analyze over 1.6 billion data points each day, to further improve manufacturing efficiency and the quality of 3D flash memory.
