ABSTRACT:
A semiconductor integrated circuit device includes a voltage drop circuit for generating a dropped voltage from a power supply voltage externally supplied to a power supply line, and a plurality of circuits respectively connected to the voltage drop circuit and driven by the dropped voltage. A switching unit, which is connected to at least one of the circuits, connects the power supply line to the above one of the circuits in synchronism with operation of the above one of the circuits. The above one of the circuits is driven by currents from both the voltage drop unit and the power supply line in synchronism with the operation thereof.
