AI memory stocks

HBM, DRAM and AI storage — the companies behind the memory that feeds every accelerator.

61 companies · 3 chain parts

Every AI accelerator is fed by memory, and the fastest kind — high-bandwidth memory (HBM) stacked beside the GPU — has become one of the tightest parts of the whole build-out. A handful of makers supply it, each new generation is sold out well ahead of production, and the advanced packaging that bonds it to the chip is itself a bottleneck. Around HBM sit conventional DRAM and the NAND/flash that stores model weights and checkpoints. Because memory is a small club of suppliers selling into runaway demand, pricing power concentrates fast — which is exactly why it shows up as a distinct exposure in the model. These are the names most exposed to the memory layer of the AI value chain.
