Abstract
The non-volatile storage solid state drive (SSD) has non-volatile memory (NVM), random access memory (RAM) capable of being accessed at a higher speed than this NVM, and a control unit for controlling accesses to the NVM and to the RAM. The control unit stores in the NVM an address translation table that translates a logical address given to access this NVM to a physical address after dividing it into multiple tables, and stores in the RAM the multiple address translation tables-sub on RAM that have been divided into multiple tables.
