According to one embodiment, a semiconductor switch includes a voltage generator, a driver, a switch section, and a power supply controller. The voltage generator is configured to generate a first potential and a negative second potential. The first potential is higher than a power supply voltage supplied to a power supply terminal. The driver is connected to an output of the voltage generator and includes a first level shifter and a second level shifter. The first level shifter is configured to output the first potential in response to input of high level and to output low level in response to input of low level. The second level shifter is configured to output the first potential in response to input of the first potential an output of the first level shifter and to output the second potential in response to input of low level of the output of the first level shifter. The switch section is configured to switch connection between terminals in response to an output of the driver. The power supply controller is configured to control the output of the voltage generator to be connected to the power supply terminal during a first period after supplying the power supply voltage to the power supply terminal and control the output of the voltage generator to be disconnected from the power supply terminal after expiration of the first period.
