It wouldn't make sense to use FRAM for ROM, since the big feature of FRAM is fast write speed. I found one DEC document that says the Flash ROM on one product is the Intel 28F008SA, an 8Mb flash chip. So I expect the VAXstation uses boring flash too, rather than costly FRAM.

What would be good for DRAM read speeds, and not care too much write speeds?

I’m thinking of keeping an LLM’s weights in a storage RAM, where it would be updated only every few months.

DRAM or SLC NAND. Be careful with read-induced disturbance on the latter, though.
