I was given a demo of a RAM disk with real disk backup in the early 
1990s.  The battery in that was supposed to last long enough to copy the 
RAM contents to the physical disk in the event of a power fail.

I never saw any of these deployed anywhere though.  I wouldn't be 
surprised if they were too expensive.
