Oh, and I forgot to mention: The width of a row could actually be pretty wide for a large storage array in a single chip. One embedded microcontroller I use has a row width of 192 bytes. (It's a 24-bit wide memory, hence the weird number.) I could imagine the row being much, much wider in a higher density flash such as what SSDs are made of.
Still, redundant row compression seems like an interesting idea to me. I'm not sure what you'd store the reverse map in, though, to make it effective, since that too needs to be stored somewhere non-volatile. This is where having a multi-tiered storage setup (volatile RAM + non-volatile RAM + flash) could be really interesting as compared to just having a PC + flash.
