Free sector manager for data stored in flash memory devices |
September 22, 2009 |
| A flash driver tracks data stored in a flash memory device through the use of logical-to-physical sector mapping. The mapping is stored in a data structure and allows data to be written into the next free physical sector in the flash memory medium. Write operations complete quickly, |

Dynamic data structures for tracking file system free space in a flash memory device |
July 25, 2006 |
| One or more secondary data structures are maintained containing mappings of logical flash memory addresses to physical flash memory addresses. Each secondary data structure has a predetermined capacity of mappings. A master data structure is also maintained containing a pointer to each o |
