OK. I thought feedback was more like that analog thing in electricity where you plug thing into itself and it amplifies but I guess it's also used in memory circuts

Have a look at the diagram for https://minecraft.wiki/w/Redstone_circuits/Memory#Input_stab.... It's doing exactly that.

again this is showing memory and not the analog feedback behavior I thought about...

They're (approximately) one and the same.

* Feedback causes memory-like effects (e.g. reverb and oscillation whine in audio systems).

* Besides maybe memresistors, memory is pretty much always implemented via positive feedback (i.e. >unity loop gain) plus some sort of saturation to prevent exponential growth (which you typically get for free in physical systems if you can keep them from exploding).

Furthermore, digital behavior is an emergent effect from analog physical systems that are designed to be bistable. Digital systems will always make use of analog physical processes "under the hood".
