In a semiconductor device, a selector selects a different reference voltage depending on whether the impedance of a transmitter or of a receiver is to be adjusted, and causes a reference voltage generator to generate the selected reference voltage. The reference voltage generator generates the reference voltage selected by the selector and applies the generated reference voltage to an impedance adjuster. The impedance adjuster adjusts the impedance of the transmitter and the impedance of the receiver, separately from each other, in accordance with the input reference voltage. |
