Abstract
An information processing device and information processing method including a management table that includes three pages. A pair of first and second pages is alternately used as a valid page and an invalid page to secure the data. The valid page is copied to a third page. Even when the power is shut off in the process of updating the page, at the next start time, the status of the data writing operation when the power is shut off is determined based on the validity and stability of the pages. Therefore, the data is restored without any corruption of valid page by using a proper restoring method.
