| 摘要 |
A semiconductor device in accordance with an aspect of the present invention includes first and second power-supply circuits each of which generates an internal power-supply voltage by converting a voltage value of a power-supply voltage into a different voltage value, a first internal circuit that receives a supply of the internal power-supply voltage from the first power-supply circuit through a first line, a second internal circuit that receives a supply of the internal power-supply voltage from the second power-supply circuit through a second line, an inter-block line that connects the first and second lines to each other, and a control circuit that operates the first and second internal circuits in a predetermined operating cycle, and controls a length of a period during which the first and second internal circuits operate simultaneously.
