Synchronous circuit

Digital circuit synchronized by clock signal

In digital electronics, a synchronous circuit is a digital circuit in which the changes in the state of memory elements are synchronized by a clock signal. In a sequential digital logic circuit, data is stored in memory devices called flip-flops or latches. The output of a flip-flop is constant until a pulse is applied to its clock input, upon which the input of the flip-flop is latched into its output.
