Abstract

PURPOSE:To keep data on a main storage device in a nonvolatile condition without increasing the load of a main arithmetic and control unit and to improve the uniformity of the keeping data at the time of a restoring processing after a system-down by providing a nonvolatile external storage device, etc. CONSTITUTION:A nonvolatile external storage device 8, which equips with a back-up power source E, is provided on a main arithmetic and control unit 1 and stores the data simultaneously with a main storage device 2. Accordingly, when a trouble is generated to a system and the keeping data of a storing area 12 of the storage device 8 are once kept through an arithmetic and control unit 9 for data keeping to an auxiliary storage device 3, it is not necessary to execute the transferring of the data to the storage device 3 at a normal time and the load of the unit 1 can be decreased. When the re-rising of the unit 1 is executed, a program 7 for restoring in the storage device 2 is traveled and the keeping data, which are copied to the storage device 3, of the storage 8 are read. Then, the data are written to a data keeping and storing area 4 and restored. Thus, the data are kept without fail and reliability is improved. Then, the re-rising of the system can be made smooth.
