Memory & Storage

HBM, DRAM, NAND, hard drives

Every accelerator is bottlenecked by how fast it can be fed data. High-bandwidth memory sits next to the GPU; DRAM, flash and hard drives hold the training data and model outputs.

How memory companies earn from AI

An accelerator is only as fast as the memory feeding it. High-bandwidth memory (HBM) is stacked next to the GPU and is made by three companies worldwide, of which Micron is the only one on this list; server DRAM and data-center SSDs (Micron, SanDisk) hold the working data; hard drives (Western Digital, Seagate) hold everything else at the lowest cost per terabyte. Memory is a commodity business with a price cycle, and in 2026 the cycle has run several times above last year's levels: Micron's quarterly revenue was $41.5 billion against $9.3 billion a year earlier.

Exposure is easiest to measure at Micron and SanDisk, which report data-center business units. The two hard-drive makers sell almost entirely to cloud customers but do not separate AI from ordinary storage, so their pages rate exposure as partial: AI is a reason hyperscalers buy more drives, not a product line.

What to watch in memory

  • Micron's fiscal Q4 report on September 30, 2026: revenue against the $50.0 billion guide and the HBM commentary set the tone for the whole category. source
  • NVIDIA's purchase commitments, which rose to $279 billion 'primarily related to procurement of memory'. That is the demand side of this category written into a supplier's filing. source
  • Price: memory margins (Micron guided gross margin near 86%) are cyclical highs. The risk in this category is the cycle turning, not demand disappearing. source
