Abstract
In a semiconductor device according to the invention, first and second voltage dropping circuits, for generating voltages respectively having smaller values than that of an external power supply voltage, are provided. The first voltage dropping circuit, which consumes relatively less power, is always in the operative mode, and the second voltage dropping circuit, which consumes more power than that of the first voltage dropping circuit, is operated during an interval other than a standby interval. The voltages generated by the first and second voltage dropping circuits are supplied to an internal power supply line in parallel with each other.
