New chips to be made in 'Optics Valley'

A new type of 3D NAND flash memory technology was released by a company based in Wuhan, Hubei province, during the Flash Memory Summit held in California on Wednesday, providing faster performance with lower costs.

Flash memory is widely used in computers and smartphones, and 3D NAND flash is a type in which the memory cells are stacked vertically in multiple layers instead of in a planar form.

The new technology, Xtacking, released by Yangtze Memory Technologies Co Ltd, uses a different architecture for making 3D NAND flash, in which the whole intellectual property is owned in China, according to Diao Shijing, the co-president of the company.
