Abstract
A forward lookup address translation table and a reverse lookup address translation table stored in a nonvolatile second storing unit are transferred as a master table to a volatile first storing unit at a time of start-up. When an event occurs so that the master table needs to be updated, difference information before and after update of any one of the forward lookup address translation table and the reverse lookup address translation table is recorded in the first storing unit as a log, thereby reducing an amount of the log.
