Abstract
The present invention provides a method of data management for a flash memory medium, characterized in that the status flag of the memory block of said flash memory medium is set as an unfinished state during operating the memory block; after finishing the manipulation, the status flag is set from the unfinished to a finished state. This method ensures that the original data in the flash memory medium will not be lost even if the false power cut occurs when writing the data into the flash memory medium. The present invention also provides a method of writing and a method of recovering the data in the flash memory medium using the above-mentioned data management method.
