Picture do not work. It is wrong setting :
Aritmetic combinator is :
Signal O + value 3
correct is:
Signal O + Signal 3
Naming convention of signals is unfortunate. On top, description could be better as cell does something else.
Proposal:
Output of the memory cell are 2 mutually exclusive signals.
In case input signal I > 0 then signal I is passed to the other side.
In case input signal I is interrupted, then signal M is passed instead as a memory of previous input value.
When input signal I is interrupted, it takes 2 ticks to switch to memory signal M.
In case input I signal lasts only one tick then memory cell start to cycle 2 previous values, tick by tick. Indefinitely.
Switching is seamless, e.g. no ticks with empty signal.
