Go to
http://www.ramtron.com they do the ferromagnetic RAM.
A year ago they were offering free samples and may still be
doing so.
FRAM is very similar to core in that a read is destructive
and you have to do a write after read but this is all done
transparently by the device.
I got the datasheets. I wish they did have the write new data option as
it would
make replacing core much simplier. With the FRAM you have to have TWO
memory cycles and early write data as well to emulate core.
