Flash Memory (NAND Flash)
Non-volatile storage that retains data without power; the technology underlying SSDs and the AI data-storage layer.
Flash Memory, specifically NAND Flash, is non-volatile storage that retains data without power, unlike DRAM. It is the technology underlying solid-state drives (SSDs), which form the high-throughput storage layer feeding AI training pipelines. The NAND market is distinct from DRAM in suppliers and cycle dynamics, though both are concentrated among a handful of manufacturers. See Memory Wall 101.
