摘要： A semiconductor memory device with a clock synchronization circuit capable of performing a desired phase/frequency locking operation, without the jitter peaking phenomenon and the pattern jitter of an oscillation control voltage signal using injection locking. The device includes a phase-locked loop that detects a phase/frequency difference between a feedback clock signal and a reference clock signal to generate an oscillation control voltage signal corresponding to the detected phase/frequency difference, and generates the feedback clock signal corresponding to the oscillation control voltage signal. An injection locking oscillation unit sets up a free running frequency in response to the oscillation control voltage signal and generates an internal clock signal which is synchronized with the reference clock signal.
