I have an idea to produce an MM-8 clone using RAM that acts like core when

Can anybody suggest a chip that will do this?
Any CMOS SRAM chips can do this, with a backup battery. I
used a IS62WV6416DBLL in a project a while ago. I did not
use in in battery-backed mode, but it could do that. You do
have to make sure that any outputs from the memory are
driven to the high-impedance state during power-off to
prevent draining the battery.
