Yangtze River Storage Xtacking Flash Process Yield Reached 99.999%

Zhongguancun online news, recently Yangtze River Storage brand Zhi state launched a new generation of flagship SSD hard disk TiPro7000 series, support PCIe Gen4, the highest reading speed of 7400MB/s, the product is equipped with Yingren Technology Rainier IG5236 main controller, support PCIe 4.0 x4, NVMe 1.4, eight-channel design, 12nm manufacturing process, this time also adjusted the package, increase the heat dissipation area, can effectively reduce the temperature under high load.

It is reported that the official also provides a detachable heat sink, aluminum material, thickness of 5 mm, covering 0.5 mm thermal conductive adhesive, claiming to be able to cool down up to 30 ° C, and perfectly compatible with PS5. At present, TiPro7000SSD has been listed on the Jingdong pre-sale, 512GB 819 yuan, 1TB 1269 yuan, pay a deposit of 30 yuan can be deducted 150 yuan, 200 yuan respectively, to the hand price of 699 yuan, 1099 yuan.

At the same time, Yangtze River Storage said that the Titan brand was renamed Zhi state, and the Xtacking architecture developed by it also added Chinese name "Crystal Stack". An important process step in Xtacking's stack architecture flash memory is wafer bonding, and the yield of this process has reached 99.999%.

In the traditional 3D NAND architecture, the peripheral circuits account for about 20-30% of the chip area, which also makes the memory density of the chip significantly reduced. As 3D NAND technology stacks to 128 layers or more, the chip area occupied by peripheral circuits may reach more than 50%. Xtacking technology places peripheral circuitry on top of the memory cell, enabling higher storage density than traditional 3D NANDs.
