Out(t) = In(t-1)

These makes no sense to me. So t fluctuates between 0 and 1 according to the clock, or does the whole bracketed statement do that? Can t be 500? Is Out being multiplied by t or is it operating on t? The way I understand this is “Out is now what In was before” but this leaves me asking 10 billion other questions.

I have built the first chip (the Bit) using the software, but I did that by constantly trying different things rather than reaching an understanding, so I’m not continuing until I have some clarity as this isn’t a recipe for understanding anything.

I have tried YouTube vids explaining memory circuits but haven’t found anything good.
