Abstract
A semiconductor device includes a high voltage generator for generating a high voltage by raising a power source voltage, a transfer circuit for transferring the high voltage to an internal circuit in response to a transfer signal, and a first discharge circuit for discharging the high voltage of an output node of the high voltage generator or the high voltage of an input node or output node of the transfer circuit when the power source voltage drops.
