Abstract:
A device includes an output circuit including a plurality of unit buffers, each of the unit buffers having an adjustable impedance; a controller circuit operable to selectively activate at least one of the unit buffers; and an impedance adjustment part operable to adjust the impedance of each of the unit buffers in response to a change of the number of the unit buffers that are selectively activated by the controller circuit.
