PURPOSE: A data driving impedance auto calibration circuit and a semiconductor integrated circuit using the same are provided to improve a data output property by maintaining data driving impedance. CONSTITUTION: In a data driving impedance auto calibration circuit and a semiconductor integrated circuit using the same, a detection block(500) detects the change of a motion property. The detection block adjusts a specific voltage according to a code signal. The detection block generates a control property voltage. A comparison block(700) compares a reference voltage with the control property voltage. The comparison block outputs a compare result signal. The code adjusting block(900) adjusts the code signal.
