Another interesting technology that would be useful for RAM carts is an SRAM with internal battery backup. Dallas Semi-conductor (and I am sure other companies) make these SRAMS. The have the same pinouts as normal SRAM IC's and are used in exactly the same way. They have the backup battery and associated circuitry build right into the chip so you don't even have to think about it. They are also not that expensive.
