Abstract
A dynamic circuit that prevents a malfunction, even when the operating temperature is high, including a pre-charging circuit connected between a power source node and a signal wiring, a plurality of discharging circuits being connected between a power source node and a signal wiring, a plurality f discharging circuit connected between the signal wiring and a ground potential respectively and for being selectively turn-ON/OFF controlled, a leakage current detecting circuit for detecting a current corresponding to a leakage current generated between the signal wiring and the ground potential in the turn-OFF state of each discharging circuit, and a leakage current correcting circuit connected between the power source node and the signal wiring and for continuously supplying to the signal wiring a leakage correction current equivalent to a leakage current of the signal wiring corresponding to a detected current of the leakage current detecting circuit during a leakage current correction period.
