Comment on Micron to boost DRAM output with $1.8bn chip fab buy

So does anyone know, is it hard to make RAM?
I’m not really a hardware person, but purely in terms of logic gates, making a memory circuit isn’t going to be hard. I mean, a lot of chips contain internal memory. I’m sure that anyone that can fabricate a chip can fabricate someone’s memory design that contains some amount of memory.
But I’m assuming that it’s not trivial to go out and make something competitive with what the PC memory manufacturers are making in price, density, and speed.
I mean you can’t do it in your garage, but if you have the facility with the machines and the staff and the knowledge then yeah it’s not hard.
There is actually a guy making CMOS transistors in his garage because he has some of the machines, but he can’t make them micro-sized and can’t make whole die sheets. (Also that’s transistors for processors, not memory, but they parallel.)
The dirty stuff not so much but if you want it clean and pure yeah
Be careful where you buy it, some DIY lithographers will cut it with ROMs.

No.
I tried once, it didn’t go well.
