PROBLEM TO BE SOLVED: To provide a non-volatile storage having a reduced manufacturing cost, having high access performance and reliability, and achieving space saving.SOLUTION: An SSD 202 includes a non-volatile NVM 205, a RAM 206 capable of being accessed at a higher speed than this NVM 205, and a control unit 204 for controlling access to the NVM 205 and to the RAM 206. The control unit 204 stores in the NVM 205 an address translation table (LPT) that translates a logical address given to access the NVM 205 to a physical address after dividing it into multiple tables, and stores in the RAM 206 the multiple address translation tables (LPT-SRs) that have been divided into multiple tables. |
