ABSTRACT:
When an operation of an internal circuit is initiated, a current is supplied from an external power supply node to a sub-power source line for a predetermined period. A semiconductor device having a hierarchical power source structure is provided, which can have a voltage variation in the sub-power source line reduced and which can recover the varied voltage speedily to a predetermined voltage level in an operating state of the internal circuit.
