In digital electronics, a flip-flop is a most elementary memory element used in several electronic circuit to store 1-bit information. A flip-flop is a basically a bistable multivibrator having two stable states. Flip-flops are made up of an interconnection of logic gates. However, a logic gate itself does not storage capability, but when several logic gates are arranged in a specific manner, they can store information. Also, flip-flop is the most fundamental building block of sequential logic circuits. The block diagram representation of a typical flip-flop is shown in Figure-1. A flip-flop has one or more inputs and two ... Read More
