> No; that’s absurd to say it’s physically impossible, it is absolutely possible to etch whatever arbitrary pattern into a physical substrate, physics pending.

Logic processes do not have the capabilities to even manufacture DRAM. It’s not about cost or yield, they just do not have the correct blocks to make DRAM. The processing to make DRAM makes it incompatible with making logic at the current speeds and densities.

There were some much older processes where you could do both, but those are about 10 years old now and we’ve long since moved on. I do not think there will be a future where you can do both.
