<P>PROBLEM TO BE SOLVED: To provide a data processing apparatus for reliably saving the data of a memory, which have not been backed up without increasing the capacity of an auxiliary power source. <P>SOLUTION: Even when a power supply from a power source circuit 9 is cut off (the deterioration of a power supply voltage is detected), data stored in an RAM module 10 are saved to SDRAMs 11 and 12 which receive the supply of a second low voltage BDL which has been backed up from a backup power source circuit 33 by using the fact that the power supply to an RAM module 10 or an ASIC 20 is continued while the power supply is interrupted. <P>COPYRIGHT: (C)2009,JPO&INPIT |
