Another option you might want to look at is the nonvoliatile SRAM modules that Dallas Semiconductor sells. They work exactly like normal SRAM chips, but they have thier own internal battery backup which makes them real easy to use. I just savaleged a bunch of them off some equipment we were getting rid of here at work, hope to put them to good use one of these days :)
