Abstract
A semiconductor device includes a control signal generation circuit and an input/output control circuit. The control signal generation circuit enters a copy operation based on a combination of logic levels of first and second operation control signals and generates a transfer control signal according to a detection result of logic levels of bits included in first internal data during the copy operation. The input/output control circuit generates first data and second data by inverting or non-inverting the logic levels of the first internal data based on the transfer control signal.
