A semiconductor device includes a first terminal which receives a signal within a predetermined potential range in a first operation mode, and receives a potential higher above the predetermined potential range in a second operation mode, a high potential detection circuit which is connected to the first terminal, and detects the high potential to generate a high potential detection signal, a second terminal which receives a command signal, a latch circuit which latches the command signal supplied to the second terminal in response to the high potential detection signal, and a third terminal which resets the latch circuit in response to a signal within the predetermined potential range supplied from an exterior of the device.
