A semiconductor storage device in accordance with the present invention includes a first SRAM cell that stores data, and a word line circuit that outputs a first control signal used to activate the first SRAM cell. The word line control circuit gradually raises the voltage level of the first control signal from a substrate potential to a first power supply potential in a first activation period, maintains the voltage level of the first control signal at the first power supply potential in a second activation period subsequent to the first activation period, and raises the voltage level of the first control signal from the first power supply potential to a second power supply potential in a third activation period subsequent to the second activation period. |
