SanDisk, Toshiba announce the world's highest capacity 3D NAND flash chips

3D NAND chip for wide use

Taking into account a vertical blaze stacking innovation that the organizations call BiCS [Bit Cost Scaling], the new glimmer memory stores three bits of information for every transistor (triple-level cell or TLC), contrasted with the past no good (multi-level cell or MLC) memory Toshiba had been creating with BiCS.

The two NAND streak makers are as of now printing pilots of 256Gb X3 chips in their new Yokkaichi, Japan creation plant. They are hoping to dispatch the new chips one year from now.

A year ago, Toshiba and SanDisk reported their coordinated effort on the new fab wafer plant, saying they would utilize the office solely for three dimensional "V-NAND" NAND streak wafers.

At the season of the declaration, the organizations reported the coordinated effort would be esteemed at about $4.84 billion when development of the plant and its operations were figured in.

In March, Toshiba declared the initial 48-layer 3D V-NAND chips; those blaze chips held 128Gbit (16GB) of limit.

The new 256Gbit glimmer chip, which utilizes 15 nanometer lithography process innovation, is suited for different applications, including customer SSDs, cell phones, tablets, memory cards, and venture SSDs for server farms, the organizations said.

SanDisk and Toshiba reported today that they are producing 256Gbit (32GB), 3-bit-per-cell (X3) 48-layer 3D NAND glimmer chips that offer double the limit of the following densest memory.
