Semiconductor device

A semiconductor device comprising:

• a first transistor of an insulated gate type and a second transistor of an insulated gate type, the first and second transistors being connected in parallel with each other;
• a charger-discharger;
• and
• a gate voltage correction circuit,
• wherein
• the charger-discharger is configured to be capable of performing
• first control in which the charger-discharger charges both of respective gates of the first and second transistors,
• second control in which the charger-discharger discharges both of the respective gates of the first and second transistors, and
• third control in which the charger-discharger discharges only one of the respective gates of the first and second transistors, and
• the gate voltage correction circuit is configured to correct respective gate voltages of the first and second transistors, and protection operation in which the first and second transistors are forcibly kept off.
