<P>PROBLEM TO BE SOLVED: To provide a microcomputer system capable of maintaining information, such as program execution states or process results, as much required under the power supply voltage supplied and maintained to the microcomputer system without saving information, such as program execution state or process results, at the time of power interruption in a non-volatile storage region or a storage region having a backup power source. <P>SOLUTION: By providing two series of fuel containers 250, 251 and controlling fuel supply to a generating part 202 by the two series of fuel containers even when a power interruption occurs, such as a power switch interruption or an unexpected power interruption, power supply to the microcomputer system is maintained as long as necessary. By arranging and constituting fuel supply to the generating part 202 by the second fuel container 251 as an auxiliary fuel container of the two series of fuel containers 250, 251 independently from a fuel interruption, problems caused by multiple interruptions of the power source are avoided. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
