Micron 256GB DDR5 RDIMM sampling at 9,200 MT/s w/1-gamma for AI servers
Key Questions
What is Micron sampling for AI servers?
Micron is sampling 256GB DDR5 RDIMMs using 1-gamma DRAM technology at speeds up to 9,200 MT/s. This is 40% faster than current production modules.
What technologies enable Micron's new DDR5 RDIMMs?
The RDIMMs use 1-gamma DRAM, 3DS stacking, and TSV for high density. They offer 40% power savings compared to dual 128GB configurations.
How does this fit into the broader AI infrastructure?
It accelerates AI/data center efficiency amid HBM shortages and hyperscaler capex boom. It reinforces Micron's DDR5 roadmap for scaling server memory needs.
