1. A semiconductor device comprising:

  • an external power supply terminal to which an external power supply voltage is supplied;

    an internal power supply line;

    first voltage dropping means, connected between said external power supply terminal and said internal power supply line, operative in at least a standby interval, for generating a first voltage having a smaller value than that of the external power supply voltage to supply the first voltage to said internal power supply line; and

    second voltage dropping means, connected between said external power supply terminal and said internal power supply line, operative in an interval other than the standby interval for generating a second voltage having a smaller value than that of the external power supply voltage to supply the second voltage to said internal power supply line.
