ABSTRACT:
The present invention relates to a semiconductor circuit device including a logic circuit and a signal line driving circuit. The logic circuit is operated at high supply voltage and outputs a signal with a high voltage amplitude. The signal line driving circuit receives a lower supply voltage and has a low-threshold transistor. With the above configuration, a signal can be transmitted at a high speed with a low voltage amplitude and low power consumption. Thus, the semiconductor circuit device including the signal line driving circuit can reduce operating current and can be operated with a low amplitude and low standby current at a high speed.
