Flip Flop F.F .

Howstuffworks, , :
"One of the more interesting things that you can do with Boolean gates is to create memory with them. If you arrange the gates correctly, they will remember an input value. This simple concept is the basis of RAM (random access memory) in computers, and also makes it possible to create a wide variety of other useful circuits Memory relies on a concept called feedback. That is, the output of a gate is fed back into the input If you follow the feedback path, you can see that if Q happens to be 1, it will always be 1. If it happens to be 0, it will always be 0. Since it''s nice to be able to control the circuits we create, this one doesn''t have much use -- but it does let you see how feedback works This circuit has two inputs (R and S) and two outputs (Q and Q'') What the logic table shows is that:
If R and S are opposites of one another, then Q follows S and Q'' is the inverse of Q.
If both R and S are switched to 1 simultaneously, then the circuit remembers what was previously presented on R and S.
There is also the funny illegal state. In this state, R and S both go to 0, which has no value in the memory sense In this circuit, there are two inputs (D and E). You can think of D as "Data" and E as "Enable." If E is 1, then Q will follow D. If E changes to 0, however, Q will remember whatever was last seen on D. A circuit that behaves in this way is generally referred to as a flip-flop "
