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.

do you have a reference to exact / realistic scaling laws for the leakage currents as function of capacitor/dielectric dimensions and access transistor dimensions?

using 4 (or 2^N) voltage levels stores 2 (or N) bits, so we can afford to make the structures larger

why would this approach make sense for NAND flash but not DRAM?

Earlier quoted context omitted.

Lowest 2012 price listed is 3.7 (2012-10-30) vs highest listed in 2026 is 5.375 (2026-2-1), which overlaps based on the margin for error involved. https://www.usinflationcalculator.com/

So you are trying to compare the lowest with the highest and not the current price. RUn that number with the current price.

The most recent price listed is from a month ago and the prior prices are increasing. So really you can roughly compare years but not Today.

There’s plenty of data to say prices in 2012 and 2016 overlap, which is wild.

In the first graph, if you hover over the DRAM line you'll notice that the most recent data points are for DDR3. One of the data points from 2025 is a 2 GB stick. This paints a more rosy picture than the situation deserves.
