Micron's 1γ fabrication technology with EUV, new HKMG, and BEOL promises to increase performance while cutting power consumption for DRAM.

I find it interesting they are boasting about the EUV process with slides, rather than the high-k material that made the capacitor size shrink possible.

Is 1γ a 8nm to 10nm node size?

RAM so fast it time traveled! I think you meant today on February 25. ;-)

Exactly that!

Article says 1γ is Micron's 6th-gen 10nm class node.

I wonder if this will mean Micron DDR5 IC will be viable for high performance kits finally. I don't think I'd move back to lower capacity modules, but it would be nice if SK Hynix had some actual competition. In theory that might knock down the prices on the higher performance kits.

Is 1γ a 8nm to 10nm node size?

Yeah it's in that general area. Due to the trouble with shrinking memory all of the manufacturers have obfuscated their process for years now. I think SK Hynix was the first of the three to use EUV which may explain their dominance in the DDR5 era.

First of all, I'm typing this from a cell phone so sorry for any sloppiness.

Typo in the main article: I assume "March 25th" is meant to be "February 25th"

For context, cell sizes are measured with 6F^2. IIRC, the previous feature size (F) for 1-beta was slightly over 13nm (as in, something like 13.1nm) which put it behind Samsung and SK Hynix which were slightly below 13nm (something like 12.9nm). Tokyo Electron's generic roadmap for investors put "12-11nm" as the feature size of 1-c/1-gamma, so it's likely in that range.

I hate those marketing names.

>30% density sounds like you can go from 24 Gb to 32 Gb, so do that please.

I went back to check, and the F for 1b/1β was 12.54nm for Samsung, 12.65nm for SK Hynix, and 13.04nm for Micron. This data is from Tech Insights using a TEM.
