ABSTRACT:
A semiconductor integrated circuit having a switching variable resistance device with combined functions of a switching device and a variable resistance device is provided. The semiconductor integrated circuit includes a supply voltage input terminal that receives a supply voltage, a pulse generating unit that receives an input pulse and generates a variable amplitude pulse in response to the input pulse during a period of time, and a switching variable resistance unit that controls a current flowing into the supply voltage input terminal in response to the variable amplitude pulse, thereby limiting an inrush current and thus substantially reducing an temporary unstable effect on the supply voltage, which may be supplied from a power source.
