More Data, Faster Speeds – KIOXIA reveals their new 2Tb QLC BiCS NAND Flash

KIOXIA has started sampling its latest 3D NAND flash to customers

Kioxia has revealed today that they have started sampling their 2Tb Quad-Level-Cell QLC NAND chips with customers. These new NAND chips feature 8th generation BiCS 3D NAND flash, which delivers increased memory density and performance to customers. Why is this important? It’s important becouse it paves the way towards larger capacity and faster QLC-based SSDs.

With this new NAND flash, Kioxia are using a 3.6 Gbps memory interface, and boasts a 12% increase in NAND layer density. Kioxia’s new NAND chips feature 218 layers, promising a 50% increase in memory density of their last-generation flash.

Today’s highest capacity Kioxia product use the company’s 5th generation QLC NAND. Now, Kioxia’s new 2Tb 8th generation QLC chips can offer a 2.3x increase in bit density. Furthermore, Kioxia has boasted a write power efficiency that is 70% higher than before.

Alongside their new 2Tb QLC chips, Kioxia is also working on a performance-optimised 1Tb chip for their customers. This chip offers users a 30% increase in sequential write performance, and a 15% improvement in read latency. These NAND chips are intended for high performance applications. This means that we can expect to see this NAND in consumer-grade SSDs and mobile devices.
