ABSTRACT:
In signal transmission lines among logic circuits employed in a semiconductor integrated circuit device, a voltage driver circuit is provided with such a wiring whose length is short, and the function of the signal receiving circuit is achieved by a logic circuit capable of responding to a voltage appearing at a terminal of the wiring. On the other hand, a source terminal of such a wiring whose length is long and whose resistance is high, is voltage-driven by the voltage driver circuit in response to the output voltage of the logic circuit. A current sense circuit is provided with a terminal of this long length wiring, which senses a current flowing through this long length wiring to be converted into a voltage. Both an output resistance of the voltage driver circuit and an input resistance of the current sense circuit are made lower than a DC resistance of this long length wiring.
