NVIDIA Vera Rubin requires HBM4 memory from three suppliers (Micron, SK Hynix, Samsung), creating critical dependency on advanced memory packaging
Jensen Huang· NVIDIA· AI· 2026-06-02· about Micron, SK Hynix, Samsung (MU, SK, Samsung Elec)
“HBM4 memory from Micron, SK Hynix and Samsung”
Why it matters
Vera Rubin is now in full production at scale with multiple major AI customers (Microsoft, Dell, CoreWeave). HBM4 memory is a critical bottleneck for agentic AI infrastructure buildout globally.
Investment implication
Micron, SK Hynix, and Samsung will see sustained demand from major cloud providers deploying Vera Rubin systems. Any supply constraint in HBM4 production could delay Vera Rubin deployments and create pricing power for memory suppliers.
