> Now to the crux of it, and I can elaborate if someone wants me to. The caps seem to be 2fF in depletion, which means that's their maximum capacitance, by my measurement. This means that there's 1248 electrons per volt. Due to the debugging frame, I can set the gate voltage and measure the current through the drain of the fg-nFETs, and the lowest that I can see is 20fA.
> 100 electrons changes the gate voltage by 80mV which is about 1 decade of current in subthreshold (diffusion current). I found that by writing 0x5A, for a b'01011010, I could always read back a current that indicated the …
