Disclosed is a data output controller that includes an enable signal controller, which generates a control signal having a predetermined pulse width in response to a DQ off signal and a write signal and generates a clock enable signal in response to a read signal and the control signal in synchronization with the control signal when the read signal is activated, and a clock generator that receives the enable signal and an internal clock signal and generates a data clock signal in synchronization with the internal clock signal during an activation period of the enable signal.
