I wonder if there are any clever ways of "remembering" the state of a flip-flop output before power down.
I have a momentary toggle switch (type (on)-off-(on)) that drives two flip-flops that control two relays. Obviously, after powering the circuit down and then back up the state of these flip-flops resets.
Are there any ways of "remembering" the state of such circuit (apart from using a microcontroller)?
