Samsung's 1-Alpha-Nm DRAM Rollout Pushes Down Micron Shares
Samsung plans to begin mass production of 1-alpha-nanometer DRAM chips by mid-2026, boosting its bit output capacity by an estimated 25%. Micron shares fell about 3% on February 9 as investors weighed increased technology competition in the high-performance memory market.
1. Samsung's Next-Gen DRAM Rollout
Samsung will start volume production of 1-alpha-nanometer DRAM chips in mid-2026, marking its most advanced memory process node. The new process is expected to increase Samsung's DRAM bit shipments by roughly 25% compared with current 1z-nanometer output.
2. Micron Share Reaction
On February 9, Micron shares declined around 3% as market participants factored in potential pricing pressure from Samsung's upcoming chip ramp. Investors are concerned that intensified competition could erode Micron's market share in high-bandwidth memory segments.
3. Competitive Landscape
Samsung’s process lead may widen the technology gap with Micron and SK Hynix, prompting a shift in customer procurement toward lower-cost, higher-density products. This dynamic could pressure overall industry DRAM ASPs and reshape vendor standings in 2026.
4. Micron's Strategic Response
Micron is expected to accelerate its own process development, including a move to 1β-nanometer DRAM in late 2026, while pursuing further cost reductions through yield improvements and capacity expansions in its U.S. fabs.
