I think the FRAM issue is a moot point. The Ramtron
FM18L08 has the same
pinout and package as the SRAM shown in the schematic.
I think you could just leave out the battery, jumper the power diode,
and install FRAM.
Same pinout, yes, but it's only rated to 3.6V according to the datasheet
here:

I don't think that will be a drop-in replacement in Steve's original
circuit.
