  • Data storing method and apparatus applied to flash memory storage device
    Patent number: 9195582
    Abstract: A data storage method applied to a flash memory storage device is provided. The method includes: identifying a first tag pointing to a storage unit storing a first data, the first data being a newly updated data; locating the storage unit storing the first data according to the first tag; storing a second data to another storage unit; pointing the first tag to the another storage unit storing the second data. A relationship between the first tag and the storage unit storing the first data is first built. The second data is stored to another storage unit different from the storage unit pointed by the first tag, and a relationship between the first tag and the another storage unit storage the second data is rebuilt. Therefore, data is efficiently stored by using a plurality of storage units to prolong a lifespan of the flash memory.
