Abstract
A semiconductor integrated circuit, including an internal circuit, a transition state voltage step-down circuit generating an internal power supply voltage supplied to the internal circuit from an external power supply voltage only for a fixed time period after the internal circuit is changed from a standby state to an active state, and a steady state voltage step-down circuit generating the internal power supply voltage from the external power supply voltage for the duration that the internal circuit is in either the standby state or the active state.
