Abstract: A method for allocating blocks within sectored EEPROM (commonly referred to as flash memory) based memory to minimize data relocation overhead and maximize sectored EEPROM lifetime. Data to be saved within sectored EEPROM is configured into data pages or blocks representing the minimum data size that is relocated within the sectored EEPROM in any given erase cycle. Multiple data blocks are contained within a single sector. A sector represents the minimum data size that is erased from the sectored EEPROM in any single erase cycle. Each block has a corresponding calculated value of volatility and new or updated data blocks to be added to the file are saved in sectored EEPROM according to a hierarchy based upon the calculated volatility of the data block. Data blocks with a calculated volatility within a predetermined threshold of the average volatility of a sector are saved within the most occupied sector containing no obsolete blocks.
