| abstract | The present invention controls the output impedance of a package constituent member to a predetermined output impedance with respect to manufacturing variations, and adjusts the output impedance of each output buffer with equal accuracy. A detection circuit detects an output impedance of a monitor output buffer including an impedance of a pattern wiring having an average wiring length of pattern wirings on a package substrate. The control signal generation circuit 4 controls the output impedances of the output buffers 1a and 1b and the monitor output buffer 2 to predetermined impedances based on the output impedance detected by the detection circuit 3.
