The present invention comprises: a data storing disk; and a flash memory successively storing data according to the output order of data outputted from an upper memory which stores data loaded from the disk. The data stored in the flash memory is reconsidered by the upper memory at a later time, first output data outputted from the upper memory is recorded on the flash memory, and second output data outputted from the flash memory is recorded on the disk. If recording the first output data on the flash memory fails, an old version of the first output data, stored in the disk or the flash memory before it was renewed, is set as the latest version, and if recording the second output data on the disk fails, an old version of the second output data, stored in the flash memory before it was renewed, is set as the latest version. [Reference numerals] (S210) Loading a page to a main memory; (S220) Renewing the page at the main memory; (S230) Outputting the page from the main memory?; (S240) Recording the page on a flash memory while guaranteeing write atomicity; (S250) Outputting the page from the flash memory?; (S260) Recording the page on a disk while guaranteeing write atomicity |
