Patent attributes
A semiconductor storage device includes a word line and a wiring, a first transistor controlled to connect the word line to the wiring, a first booster circuit configured to boost an output voltage thereof to a first voltage, a second transistor controlled to connect the first booster circuit to the wiring, and a control circuit configured to control the first booster circuit, and the first and second transistors during a read operation. During the read operation, the control circuit controls the first booster circuit to start boosting its output voltage to the first voltage while controlling the second transistor to connect the output of the first booster circuit to the wiring so that a voltage of the wiring rises together with the output voltage. After the output voltage has reached the first voltage, the control circuit controls the first transistor to connect the word line to the wiring.
