Abstract
According to the present invention, a synchronization circuit, which receives a plurality of input signals and a sync signal and performs a predetermined operation corresponding to said input signals in synchronization with said sync signal, comprising: a transition detector for detecting each transition of said plurality of input signals and for generating transition detection signal indicating that said transition occurs; and an internal sync signal generator for, upon the receipt of said sync signal, supplying an internal sync signal to said synchronization circuit when said detection signal indicate that said transition occurs, and for ceasing to supply said internal sync signal to said synchronization circuit, regardless of whether said sync signal is received, when said transition detection signal does not indicate that said transition occurs. According to the present invention, power consumption accompanying an unwanted, repeated operation can be eliminated.
