Flip-flop (electronics)

In digital circuits, a flip-flop is a kind of bistable multivibrator, an electronic circuit which has two stable states and thereby is capable of serving as one bit of memory. Today, the term flip-flop has come to generally denote non-transparent (clocked or edge-triggered) devices, while the simpler transparent ones are often referred to as latches.
A flip-flop is controlled by (usually) one or two control signals and/or a gate or clock signal. The output often includes the complement as well as the normal output. As flip-flops are implemented electronically, they require power and ground connections.
History
The first electronic flip-flop was invented in 1919 by William Eccles and F. W. Jordan. It was initially called the Eccles-Jordan trigger circuit and consisted of two active elements (radio-tubes). The name flip-flop was later derived from the sound produced on a speaker connected with one of the back coupled amplifiers output during the trigger process within the circuit.
Implementation
Flip-flops can be either simple (transparent) or clocked. Simple flip-flops can be built by two cross-coupled inverting elements – transistors, or NAND, or NOR-gates – perhaps augmented by some enable/disable (gating) mechanism. Clocked devices are specially designed for synchronous (time-discrete) systems and therefore one such device ignores its inputs except at the transition of a dedicated clock signal (known as clocking, pulsing, or strobing). This causes the flip-flop to either change or retain its output signal based upon the values of the input signals at the transition. Some flip-flops change output on the rising edge of the clock, others on the falling edge.
Clocked (non-transparent) flip-flops are typically implemented as master-slave devices where two basic flip-flops (plus some additional logic) collaborate to make it insensitive to spikes and noise between the short clock transitions; they nevertheless also often include asynchronous clear or set inputs which may be used to change the current output independent of the clock.
