Abstract: According to one embodiment, a voltage generation circuit includes a first boost circuit, a voltage division circuit, a first detection circuit, a capacitor and a first switch. The first boost circuit outputs a first voltage. The voltage division circuit divides the first voltage. The first detection circuit is configured to detect a first monitor voltage supplied to the first input terminal, based on a reference voltage which is supplied to a second input terminal of the first detection circuit, and to control an operation of the first boost circuit. The capacitor is connected between an output terminal of the first boost circuit and the first input terminal of the first detection circuit. The first switch cuts off a connection between the capacitor and the first detection circuit, based on an output signal of the first detection circuit, until the first voltage is output from the first boost circuit.
