Kioxia and Sandisk push NAND density with BiCS10 QLC demo

The announcement is a technology-roadmap signal for NAND rather than an immediate pricing event. Higher density gives suppliers a path to more bits per wafer once the process is commercialized, which can improve cost structure for SSDs and other flash products. The timing of that benefit depends on yield, product qualification, and market demand, but the demonstration reinforces that Kioxia and Sandisk are trying to stay competitive against Samsung, SK hynix, Micron, and YMTC in high-layer-count NAND.
