AI Memory (HBM & DRAM)

Three suppliers make essentially all HBM. Each HBM bit consumes several times the wafer area of standard DRAM, crowding out conventional supply.

DRAM wafer→TSV stack→HBM cube→Co-package

What would prove us wrong. Weakens if HBM inventory builds and pricing softens while GPU shipments rise.

Peers at the same bottleneck
