In my experience with parallel FRAM, it’s as fast as SRAM and is a drop in replacement with the same timing.

A lot of folks have replaced battery backed SRAM with FRAM on game consoles.

Holy cow thats cool. So It's like an expensive nonvolatile replacement for volatile memory. I wonder if in the future there could be computers with no sense of "memory vs storage", that it would all just be a single contiguous "memory".

Instead of turning off the computer and hibernating, you just turn off the LCD backlight and the IO.

While implemented virtually rather than physically, two well-known (and very different) examples of systems that unify memory and secondary storage under a single addressing scheme are Multics (1969) and the IBM System/38 (1978).

Note that the present-day IBM i née AS/400 is a direct descendent of the System/38.

You would still need to turn the CPU off though. Or do you suggest replacing the registers and caches and all other volatile memory with this stuff?

It would burn out in a few hours.
