ABSTRACT:
According to an embodiment of the present invention, a clock synchronization apparatus includes a delay-correcting circuit which is supplied with an initial voltage, compares a phase of an external clock with a phase of an internal clock output from a clock synchronizing unit, generates a control signal for correcting the phase of the internal clock on the basis of a difference between the phases of the external clock and the internal clock, and supplies the control signal to a replica delay unit of the clock synchronizing unit.
