1. A semiconductor device having a plurality of core logic elements, comprising:

  • a voltage regulator means, adapted to receive an external voltage and a reference-level voltage, for generating a first voltage having a magnitude between said external voltage and said reference-level voltage;

    a core logic power supply means for generating a second voltage, said second voltage having a magnitude between said external voltage and said reference-level voltage; and

    selection means for supplying said first voltage to said core logic elements in response to one state of a control signal and for supplying said second voltage to said core logic elements in response to another state of said control signal.
