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 |

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 |
