Abstract
A storage apparatus includes a flash memory, a second memory for storing an address translation table, and a control section. The flash memory is formed of multiple pages, each having a spare area, and data are stored on a page-by-page basis. The control section has the functions of: saving the table to the flash memory; when writing/updating data, storing the user data, recording, in the table, a correspondence between a logical page address and an address of a page in which the data is stored, and storing information for identifying the corresponding logical page address in the spare area of the page; when the apparatus is started, detecting pages to which data was written after the most recent saving of the table; and scanning the spare area of each page detected and reproducing a state of the table as updated after the most recent saving to reconstruct the table.
