question is mixing up volatile and non-volatile

Copy edited (but can "DRAM" be singular?).

| Mar 31, 2018 at 10:25 | comment | added | Harry Svensson | @peufeu If I recall correctly, the capacitor (gate) of the NANDs are pulled really high or very low (in V) to force a really strong 1 or a really strong 0. And every time you change the charge in the gate you destroy the gate slightly. In analog FPGAs you set a specific voltage at the gate which makes it behave more like a resistor, imagine an inverting amplifier (op-amp), but instead of resistors, you use two transistors with a specific charge on the gate. - That's how I think it is. I'm no expert though. | |

| Mar 31, 2018 at 10:15 | comment | added | Harry Svensson | This question would be much better if it asked why the capacitors in DRAM needs to be updated, yet the capacitors in the gates in analog FPGA's somehow retains their charge. | |
