Abstract
It is an object to realize a synchronization circuit with small size and low consumption power which enables capturing and phasing of external data without running external clock in parallel. Internal clock (2) is delayed by a delay line (1) to produce delay clocks (3), and one of the delay clocks (3) having its rise almost corresponding to that of an external data signal (6) becomes a select clock (5). An elastic store circuit (7) is a circuit which controls a row of D-latches with a row of C elements. Thus the elastic store circuit (7) captures the external data signal (6) with enough set up hold time at timing of the select clock (5) and then outputs the captured external data as an internal data signal (8) in synchronization with the internal clock (2).
