From Micron, everything up to their 1-beta node is DUV. Their 1-gamma node they debuted last year is the only EUV node they have. If you bought a Micron-based DDR5 RAM stick a year ago it would have been DUV and you could get those up to DDR5-8000. 1-gamma increases that to DDR5-9200, so if you can live with ~15% less performance DUV is good enough.
