ABSTRACT:
Disclosed is a voltage switch circuit of a semiconductor device. The subject voltage switch circuit can be used to apply voltage to a semiconductor memory device control circuit. The voltage switch circuit according to an embodiment includes five transistors and a capacitor. An output terminal of the subject circuit outputs VSS when VDD is applied to an input terminal, and outputs a boosted operating voltage when VSS is applied to the input terminal.
