A semiconductor device comprises a first circuit outputting a signal to a first signal line, a first FET applied with a driving signal and having a gate electrode connected to a first node, a second FET controlling an electrical connection between the first signal line and the first node, a third FET amplifying a signal of the first node, a second circuit precharging the first signal line, and a voltage control circuit. A gate capacitance of the first FET is controlled in response to a voltage difference between the first node and the driving signal. The voltage control circuit shifts a potential of the driving signal when the second FET is non-conductive after the signal of the first-circuit is transmitted to the first node, and performs an offset control for the driving signal so as to compensate a variation of a threshold voltage of the first FET.
