MRAM is the first step from electronics to spintronics. It's nonvolatile,
so static designs are possible. Slightly beefed up MRAM cells can be used
for reconfigurable logic gates.
A lot of CPU power dissipation is in the cache, so a MRAM version
of it would save energy. (I personally wouldn't bother with the
cache and put MRAM main memory directly on the CPU die).
