ABSTRACT:
A semiconductor device includes a memory and a power voltage interrupter configured to interrupt an external power voltage applied to circuitry of the semiconductor device responsive to a Deep Power Down (DPD) command signal generated in a DPD mode of the memory. A power voltage shifter is configured to shift a power voltage in the circuitry to a specific level responsive to the DPD command signal.
