Abstract:
1. A semiconductor device, comprising: a high voltage generator configured to generate a high voltage by raising a power source voltage; a transfer circuit configured to transfer the high voltage to an internal circuit; and a first discharge circuit configured to discharge 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, wherein the first discharge circuit comprises: a first diode configured to receive an enable signal; a first transistor comprising a first drain and a first gate, wherein the first drain is coupled to the input node or the output node of the transfer circuit and the first gate is coupled to an output terminal of the first diode; and a second diode coupled between a source of the first transistor and a power source voltage terminal to which the power source voltage is supplied.
