Semiconductor device

A semiconductor device comprising:

• an electrode;
• a pull-up circuit and a pull-down circuit that control a voltage of the electrode in response to input data;
• an internal circuit that outputs the data supplied to the pull-up circuit and the pull-down circuit;
• a control circuit configured to be able to execute an operation of the internal circuit and a calibration operation to adjust output impedances of the pull-up circuit and the pull-down circuit;
• and
• a clock signal generation circuit that supplies a first clock signal to the control circuit in a state where the calibration operation is in execution, wherein
• when an instruction to execute the calibration operation is input during execution of the operation of the internal circuit, the clock signal generation circuit outputs the first clock signal in a first period during execution of the operation and does not output the first clock signal in a second period during execution of the operation in a time period from the input of the instruction to completion of the calibration operation.
