As early as September 2019, YMTC officially announced that the company has started mass production of 64-layer 256 Gb TLC 3D NAND flash memory based on the Xtacking architecture to meet the needs of mainstream market applications such as solid-state drives and embedded storage. This is the first in China. 64-layer 3D NAND flash.

At the annual meeting of market partners held by YMTC on January 16 this year, YMTC stated that the storage density of its 64-layer flash memory is the highest in the world, and the gap compared with the 96-layer flash memory of its friends is within 10%. In addition, it was revealed that its own brand 64-layer consumer-grade solution products will be launched in the second half of this year.

According to public information, from 2017 to 2019, YMTC has successively launched 32-layer and 64-layer 3D NAND flash memory chips and memory solutions. It is worth mentioning that on April 10, 2020, Changjiang Storage officially announced that its 128-layer QLC 3D NAND flash memory (model: X2-6070) has been successfully developed and has been verified on terminal storage products such as SSDs from many controller manufacturers. .
