PURPOSE:To obtain a computer system which is operated at a high speed, and which is not affected by a vibration or the like, and to allow the computer system to necessarily operate the data save of a main memory. CONSTITUTION:A volatile IC memory 2 is used as a main storage medium, and a direct-read-after-write type disk 1 is used as a nonvolatile storage medium for backup. Then, when an operator cuts a main power source without operating the data save at the time of the completion of a processing, an alarm is generated by an alarm generating part 9, and the data save is urged. And also, a power by an incorporated battery 7 is applied to the IC memory 2 in order to hold the storage content. |
