alt Hacker News>Modern RAM is made in fabs, which are ridiculously expensive to manufacture. Modern EUV lithography machines cost around 500M each. They're manufactured by hand. Only one company in the world knows how to manufacture them right now.
You're wrong here. You don't need the most cutting edge ASML EUV machines to make RAM. Most RAM fabs still use standard DUV.

Are DUV machines cheap and easy to manufacture? I suspect if they were, we'd see a lot of cheap RAM hit the market.
Maybe some RAM chips don't need EUV lithography. but I suspect I'm still right about the economics.

Ah. Please check that. Which types of DRAM can be made in a DUV fab? Obviously the older ones, but are those obsolete for new computers. This really matters.
