Micron Pre-commits 75% of 2027 Memory Output as HBM Demand Exceeds DRAM

Micron and Samsung executives confirmed the memory shortage will extend at least through 2028. Mehrotra told investors that demand for HBM and server DRAM exceeds available supply, with new clean rooms opening only in 2028 and gradual production ramps limiting output growth. Node transitions deliver smaller productivity gains, and the shift from HBM3E to 4/4E further restricts supply expansion.

Seventy-five percent of Micron's 2027 output is already committed, and most current sales discussions cover 2028 allocations. Manufacturing capacity is directed toward AI accelerators, reducing DRAM available for consumer devices. This matches patterns seen in prior cycles where server and AI demand crowded out PC and mobile supply.

The allocation data indicates sustained price pressure and potential delays for consumer RAM modules through 2028. Samsung's parallel statements reinforce that HBM demand growth outpaces overall DRAM capacity additions, confirming the shortage is structural rather than cyclical.

Operational impact includes higher module prices for PCs and smartphones and extended lead times for system builders reliant on non-HBM DRAM.
