Toshiba and SanDisk build factory for production 3d flash module 1TB




Toshiba and Sandisk begin in September with the construction of a new facility for the production of 3D NAND flash. In 2016, the first chips to roll off the assembly line, and five years later the modules stacked memory must have a capacity of 1TB.

Toshiba announces the current Fab 2 at its Yokkaichi location, which is used for demolition to make way for a new facility that 3D NAND should produce. produce regular 2d-nand, Manufacturers were previously still plans to build Fab 2 for 3D NAND production and those yet to be started this year. The new fab is built. Together with Sandisk In the summer of 2015, the new plant should be ready and during the transition from 2D to 3D nand the cleanroom prepped. These should be ready in 2016.

Demolition and construction amounting to 700 billion yen, would be converted 5 billion Euros and Toshiba and Sandisk would each take half of these costs account. The new Toshiba and Sandisk Fab should bring in a better competitive position versus Samsung, SK Hynix and Micron. Samsung has already started producing 3D nand flash, SK Hynix would begin late this year and Micron has recently converted a dram factory for NAND production.

Conventional NAND memory is made up of chips that consist of a single layer of transistors. In a chip package are often a number of chips stacked together, but these are separate chips, while in 3d nand multiple layers of transistors on a single chip are integrated. This stacking involve significantly higher storage capacity along with it. NAND Flash is used among other SSDs, USB sticks and memory cards. “Five years after the start of the new plant we want to produce 1TB products,” says a spokeswoman for Toshiba to AFP. It is unclear whether she is referring to individual chips, whose capacity is usually specified in bits, or modules, such as MMC. Even before the transition to 3D nand Toshiba makes the step from 19nm to 15nm-production. In June, the mass to start this, claiming EETimes, the cost should be lower. The 15nm production is used for 128Gb chips.
