[edit] Flip-flops

A flip-flop is a circuit which exists in one of two states and so can store information. A simple flip-flop can be defined in terms of two NAND logic gates. Flip-flops are non linear circuits, meaning the the output from one of its gates is fed 'back' to be processed with the input signal. Because flip-flops operate on an input signal mixed with this previous output signal their own outputs are dependent upon their previous state.
