Claim 7:
8. The semiconductor device of claim 7, wherein the calibration control circuit is configured to:
provide the variable current source with a start value of the current adjustment code in a state in which switching control signals for closing the third switch, the fifth switch, and the sixth switch and for opening the first switch, the second switch, and the fourth switch have been provided to the calibration circuit,
increase the value of the current adjustment code when a logic level of an output signal that is transmitted by the comparing circuit is not changed and provide the variable current source with the increased value, and
set, as a value of the calibration current, a current value corresponding to a value of the current adjustment code when the logic level of the output signal that is transmitted by the comparing circuit is changed.
