Claim 0:
1. A semiconductor storage device comprising:
a first memory transistor;
a first transistor electrically coupled to a gate electrode of the first memory transistor;
a first voltage supply line electrically coupled to the gate electrode of the first memory transistor through the first transistor;
a first signal supply line electrically coupled to a gate electrode of the first transistor;
a first capacitor electrically coupled to the gate electrode of the first memory transistor without passing through the first transistor; and
a first wiring coupled to a current path between the gate electrode of the first memory transistor and the first transistor through the first capacitor,
wherein, in a write operation on the first memory transistor,
at a first timing, a voltage present on the first voltage supply line is a first voltage, a voltage present on the first signal supply line is a second voltage, and a voltage present on the first wiring is a third voltage,
at a second timing after the first timing, the voltage present on the first signal supply line decreases from the second voltage to a fourth voltage lower than the second voltage, and
at a third timing after the second timing, the voltage present on the first wiring increases from the third voltage to a fifth voltage higher than the third voltage.
