<p><P>PROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit which further reduces leak currents while holding an internal state, and to provide an internal state saving recovery method of the semiconductor integrated circuit. <P>SOLUTION: A semiconductor integrated circuit includes a first circuit (120) including a third circuit (122) and a fourth circuit (124), and a second circuit (110) to control the power-on/off of a first power supply (MPW) which supplies power to the first circuit (120). The third circuit (122) stores an internal state in a flip-flop group (140) where holding information is erased by the power-off of the first power supply (MPW). The fourth circuit (124) store the internal state in a retention flip-flop group (150) which stores information before the power-off of the first power supply (MPW) and recovers it when the first power supply (MPW) is powered on again. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
