Abstract
In one embodiment, a semiconductor storage device includes a memory cell, a sense amplifier, a bit line, a pre-charge circuit, and a power-supply-voltage switching circuit. The memory cell is configured to store data. The sense amplifier is configured to amplify a signal from the memory cell. The bit line is configured to transmit the signal from the memory cell to the sense amplifier. The pre-charge circuit is configured to pre-charge the bit line. The power-supply-voltage switching circuit is configured to switch a voltage of a power supply and to actuate the sense amplifier after the bit line is pre-charged by the pre-charge circuit, wherein the power-supply-voltage switching circuit is configured to switch the voltage of the power supply to be larger than a voltage during the pre-charge by the pre-charge circuit.
