Also check out Freescale's MRAM parts. They have

I recall reading about FS's MRAM technology; I hadn't realized that
they were producing them yet. One aspect of MRAM that I might find a
bit worrisome is that it does seem to have a certain sensitivity to
external magnetic fields. I have no idea if this is a real issue.
On the Ramtron parts, I forgot to mention that some families have a
software write-protect feature. So using one as ROM+RAM is very
attractive.
A very clever idea is Ramtron's integration of FRAM with an 8051
core. I can see all sorts of possibilities with embedded
applications being able to pick right up after a power interruption.
