Free sector manager for data stored in flash memory devices |
July 18, 2006 |
| 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, |

Monitoring entropic conditions of a flash memory device as an indicator for invoking erasure ope |
September 16, 2003 |
| Erase operations are performed on a flash memory device by monitoring the entropic nature of the flash memory device. In one implementation, flash abstraction logic, tracks how many physical sectors are free to receive data; track how many physical sectors contain data that is dirty, and |
