ABSTRACT:
A semiconductor integrated circuit device is connected to an external reference resistor, including an impedance control circuit for generating impedance control codes variable with impedances established by the external reference resistor. An input circuit receives an external signal through an input transfer line and forwards the external signal to an internal circuit. A termination circuit terminates the input transfer line in response to at least one of the impedance control code. An output circuit drives an output transfer line in accordance with an output signal. Impedance is variable with the control codes.
