  • Control method used in and-gate type system to increase efficiency and lengthen lifetime of use
    Publication number: 20030056141
    Abstract: The present invention relates to a flash memory and, more particularly, to an and-gate type flash memory, wherein a plurality of data storage units are provided, each of the data storage units is partitioned into a plurality of sectors, and an ECC data directly abuts behind each of the sectors to store the ECC of the sector, thereby shortening the access time of data when the data storage unit is not filled. At least a dynamic spare storage unit not detectable by a mainframe is provided in the data storage unit. When a sector of a flash memory is damaged, a control device is used to store the data in the damaged storage unit into the dynamic spare storage unit, thereby decreasing the number of damaged storage units detectable by the mainframe to relatively lengthen the lifetime of use of the flash memory.
