I kept having this sense of deja-vu as I read the article. This is essentially how the persistent store of the Apple Newton worked. Pretty neat. Our stuff supported vanilla battery-backed RAM, and we also supported memory-mapped flash (which has implications for how you represent the object state, since you can only flip bits in one direction without an expensive and destructive erase operation). Recovery after a crash was essentially a read pass of the whole device, which was fine for the storage capacities of the day, at memory-bus speeds.
