The example embodiments provide a data output buffer circuit which includes a pre-driver configured to adjust a slew rate of an input signal, a main driver configured to output signal supplied from the pre-driver, and a ZQ calibration circuit configured to control the pre-driver so as to decrease the slew rate when an operation voltage increases, and increase the slew rate when the operation voltage is decreased.
