发明名称 Memory control apparatus, content playback apparatus, control method and recording medium
摘要 A data storage apparatus is provided that realizes a measure against deterioration of a flash memory in which integrity check data is stored. A content playback apparatus (1000) uses a hash value of playback history information as integrity check data (confirmation data) for confirming whether the playback history information has been falsified. A first address calculation unit (1004) and a second address calculation unit (1006) determine a read-in address and a storage destination address for the integrity check data, with use of the hash value. Accordingly, the storage destination addresses can be diffused, thus enabling preventing deterioration of the flash memory.
