<p><P>PROBLEM TO BE SOLVED: To provide a structure reducing power consumption in a semiconductor integrated circuit. <P>SOLUTION: A clock generating part performing clock signal generation processing and a data processing part inputting a clock generated by the clock generating part and performing data processing are separated. Supply power to the clock generating part is made at a low voltage (0.8 V, for example) which is relatively lower than that of the data processing part. Power consumption of the whole circuit is reduced with such structure. Since high voltage (1.2 V, for example) is supplied to the data processing part, the data processing part can perform data processing at a high operation frequency. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
