PURPOSE: A semiconductor memory device and an operating method thereof are provided to remove a glitch in refresh operation period by restricting a period in which a glitch is generated. CONSTITUTION: In a semiconductor memory device and an operating method thereof, a control signal generator generates a control signal. The control signal is activated in refreshing. A clock control unit(502) restricts the toggling operation of an internal clock signal. The synchronization unit synchronizes an input signal in response to the output signal of the clock control unit. A clock buffering unit(501) generates an internal clock signal. A clock enable buffering unit(504) buffers the clock enable signal. |
