is multi-level DRAM worth considering? storing multiple voltage levels per DRAM capacitor?
If it were possible, it would have been done already. The issue is the capacitors are already tiny, and barely can prevent a single bit decaying before refresh.
If you care about only capacity and cost yes, but not if you care about performance.
