Abstract

See full text

A semiconductor device may include a calibration circuit and an output circuit. The calibration circuit may generate a calibration code by performing an impedance calibration operation, and may generate a correction calibration code by inverting or maintaining logic levels of the calibration code based on the calibration code. The output circuit may generate an output signal based on an input signal and the correction calibration code.
