3D NAND

Kioxia (formerly Toshiba Memory), has expanded its lineup of embedded UFS (eUFS) storage with a 512 GB device based on the company’s BiCS 3D NAND flash. The chip is rated to support a very wide range of operating temperatures along with special features that increase its reliability and endurance. Kioxia’s eUFS 512 GB drive for automotive applications uses the company’s specially developed controller as well as BiCS 3D TLC NAND flash memory. The chips are compliant with the UFS 2.1 HS-G3 specification and can use two full-duplex HS-Gear3 lanes with a 5.8 GT/s data transfer rate per lane, which means a hypothetical maximum bandwidth of 1200 MB/s (assuming that pSLC caching and other performance-boosting methods are used, of course). Other members of the automotive eUFS...
