Updating of flash memory pages in computer memory system |
| 摘要 |
To update a paged flash memory, a page Pn of the flash memory (4024) is copied as an image page into RAM memory (4022), and the image page is updated and written back into a different page in the flash memory. A main record table (122) is held in a separate non-volatile memory (EEPROM 4026), identifying valid pages in the flash memory, and updated when a page in the flash memory has been updated. The main record table includes a CRC error detection section, and is copied into a back-up record table (123) immediately after it has been updated. |
