A synchronization circuit includes a measurement unit configured to measure a difference between an initial delay amount of an input clock signal and an initial delay amount of a feedback clock signal and generate a phase difference detection signal, an initial delay time setting unit configured to generate an initial delay time setting signal in response to the phase difference detection signal, a shift register configured to generate a shift signal in response to the initial delay time setting signal, and a delay chain having an initial delay time set in response to the shift signal.
