A circuit for controlling driver strengths of a data and a data strobe in a semiconductor device comprising: a control signal generating unit which generates a first control signal in response to a first address code, generates a second control signal in response to a second address code, and generates a third control signal in response to a third address code; a data driver strength control unit which is selected in response to the first control signal, controls a driver strength of an input data in response to the second control signal, and finely adjusts the driver strength of the input data in response to the third control signal; and a data strobe driver strength control unit which is selected in response to the first control signal, controls a driver strength of an input data strobe in response to the second control signal, and finely adjusts the driver strength of the input data strobe in response to the third control signal.
