<p><P>PROBLEM TO BE SOLVED: To suppress power variation accompanying fast operation of a logic circuit. <P>SOLUTION: A semiconductor device includes: a capacitor which is supplied with a first inter-line voltage between a first line and a second line and with a second inter-line voltage higher than the first inter-line voltage between the first line and a third line, and which has a first capacitance value provided between the third line and first line; a current limiting element which is arranged between the capacitor and third line to limit a current flowing into the capacitor from the third line; a first switch element connected between the second line and the capacitor; and a voltage detector controlling the first switch element according to the first inter-line voltage. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
