A bit harsh. It's just information outdated by a year. The majority of DRAM by all big manufacturers is still on DUV tech AFAIK. Micron's "1-gamma" is pretty new. It's been less than a year since Micron started shipping DRAM based on that process.
And to the OP's comment: CXMT won't be making stuff for an Nvidia H100 any time soon haha, but there's a lot of stuff out there that's not that.
Micron's FQ1 2026 report says they expect their 1-gamma process (uses EUV) to the be the majority of their bit output by the second half of the year. The same report says they've already begun sampling 1-gamma parts to OEMs, so they must have a fab somewhere using EUV already.
The Boise plant is being reactivated and is not ready for EUV production yet. The Syracuse plant won't be running until 2030. Their Japan and Taiwan fabs are scheduled for the 1-gamma rollout.
Micron s/uses/“will use” ASML’s EUV machines[0] in New York. Micron shares some info on their EUV DRAM process[1].
DRAM composed 80% of Micron’s revenue, NAND is about 20%.
