摘要：
According to the present invention, there is provided a semiconductor integrated circuit comprising: a power controller which outputs a voltage select signal for selecting one of at least two types of voltages; a power supply voltage controller which generates and outputs a power supply voltage at an arbitrary voltage change rate on the basis of the voltage select signal; and a circuit portion which receives the power supply voltage and performs processing, wherein said circuit portion keeps operating while said power supply voltage controller is outputting the power supply voltage generated at the arbitrary voltage change rate.
