Kioxia and Sandisk sample world's densest 3D NAND

Kioxia and Sandisk have announced the sampling of their latest 3D NAND flash memory, featuring a 332-layer stack with industry-leading areal density and performance. The 10th Generation BiCS 3D TLC NA... Read original →

Kioxia and Western Digital’s 332-layer BiCS10 NAND marks a strategic pivot from cost-driven scaling to performance- and efficiency-optimized architectures. This leap pressures Samsung and Micron to accelerate EUV adoption in NAND front-end processes and may force SK hynix to reassess QLC viability in enterprise storage. YMTC, despite its 232-layer volume production, faces a genuine generational gap in read latency and power efficiency. Geopolitically, concentrating advanced output in Japan’s Kitakami Fab 2 mitigates U.S.-Japan export control risks but raises supply chain barriers for non-allied markets. Over the next 18 months, a mismatch will emerge: PCIe 6.0 controllers are ready, yet high-yield 300+ layer NAND remains scarce—widening the profitability chasm between tier-1 and tier-2 players in data center SSDs.
