| 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 |
| 20080307152 | Memory Module, Memory Controller, Nonvolatile Storage, Nonvolatile Storage System, and Memory Read/Write Method - In a storage having a nonvolatile RAM of destructive read type, the number of restorations attributed to data read from the nonvolatile RAM is decreased, and the overall life of the storage is prolonged. In a storage having a nonvolatile RAM of destructive read type and a volatile RAM and holding the same data in the nonvolatile and volatile RAMs, data is read out of the volatile RAM in reading and data is written in both volatile and nonvolatile RAMs in writing. | 12-11-2008 |

| 20090100290 | MEMORY CONTROLLER, NONVOLATILE MEMORY DEVICE, NONVOLATILE MEMORY SYSTEM, AND DATA WRITING METHOD - A nonvolatile memory device comprises a nonvolatile memory and a memory controller. The nonvolatile memory includes the same memory cells striding over a plurality of pages. A page information instruction part has the page structure information of the nonvolatile memory. According to this information, a related page identification part identifies a page (related page) in which the data may change. The relation data stored in the related page are temporarily stored into a save memory before an error occurs, and if an error exists, these relation data are used to repair the data that have changed. By this method, in a memory device using a nonvolatile memory including the same memory cells striding over a plurality of pages, even if an error occurs during data writing, the error is repaired and the reliability can be ensured. | 04-16-2009 |
| 20090210612 | MEMORY CONTROLLER, NONVOLATILE MEMORY DEVICE, AND NONVOLATILE MEMORY SYSTEM - In rewriting processing of logical sectors, data of the transferred logical sectors are temporarily stored in a memory buffer. When the buffer memory has been full filled with data, the data is written into a flash memory. In rewriting processing for the flash memory including a writing unit (page) having a capacity larger than a minimum writing unit (sector) from outside, the number of executions of the evacuation processing can be reduced and the fast data rewriting can be performed. Thus, it is possible to rationalize the evacuation processing for old data caused in the rewriting in units of sectors and to improve the data rewriting speed. | 08-20-2009 |
