20080250188 | Memory Controller, Nonvolatile Storage, Nonvolatile Storage System, and Memory Control Method - A physical area management table (105) and a pointer table (106) are stored in a nonvolatile auxiliary storage memory (107). When a logical-physical conversion table (108) is updated (restored) in a main storage memory (140), the restored area is determined in a re-arrangement way by the pointer table to avoid rewrite concentration on the main storage memory (140). Immediately after data is written in the main storage memory (140), the state of the physical block on the physical area management table (105) is updated. Consequently, even if power interruption occurs, it is possible to reliably judge if the data is valid or not. | 10-09-2008 |
