Abstract
A semiconductor device of an embodiment includes a buffer configured to perform data transmission by turning on and off a first output transistor group and a second output transistor group; a first correction circuit configured to calibrate a resistance value of the buffer by controlling an on-off state of each of first transistors of the first output transistor group; a second correction circuit configured to calibrate the resistance value of the buffer by controlling an on-off state of each of second transistors of the second output transistor group; and a control circuit configured to cause the calibration by the first correction circuit to be performed in a non-communication duration other than a duration of data transmission from the buffer and cause the calibration by the second correction circuit to be performed in a duration other than a duration of the calibration by the first correction circuit.
