A system supports flash memory having addressable locations. The system uses a compactor that periodically advances through a circular sequence of the flash memory locations organized as blocks and clears the blocks as it advances through the memory locations. In another described implementation, a system uses a write pointer that advances through the circular sequence of the flash memory locations. The write pointer indicating one or more memory locations that are free to receive data after the write pointer advances. Accordingly, the flash memory medium is organized as a continuous circle of addresses, whereby clear and write operations are handled in a continuous and repeating circular manner to achieve uniform wear leveling through a flash memory medium. <IMAGE>A system supports flash memory having addressable locations.
