Kioxia and Sandisk Unveil 9th-Generation QLC 3D Flash Memory for AI Infrastructure

Quick Report

Kioxia and Sandisk unveiled their 9th-generation 2 Tb QLC 3D flash memory technology designed to support AI-driven infrastructure and cloud workloads. The new technology leverages their CBA (CMOS directly Bonded to Array) architecture to achieve a 4.8 Gb/s NAND interface speed—a 33% improvement over the previous 8th-generation design.

Compared with 8th-gen 2 Tb QLC, the 9th-generation technology delivers higher write and read bandwidth through a 6-plane architecture, improved power efficiency for both reads and writes, and better capital efficiency in manufacturing. The CBA platform's flexibility allows Kioxia and Sandisk to independently advance CMOS and memory technologies in parallel, enabling faster innovation cycles that match the rapid pace of AI adoption and evolving storage demands.
