Abstract
Such a device is disclosed that includes an internal voltage generating circuit generating an internal voltage by lowering an external potential and supplying the generated internal voltage to a power supply line, a switch being connected between a grounding wire to which a ground voltage is supplied and the power supply line, and a one-shot signal generating unit controlling turning on and off of the switch, wherein the one-shot signal generating unit brings the switch into conduction synchronously with start of generating the internal voltage by the internal voltage generating circuit.
