1. A method for accessing a storage unit of a flash memory, performed by a processing unit, comprising:

  • after all messages within a RAID (Redundant Array of Independent Disk) group are programmed, determining whether a vertical ECC (Error Correction Code) within the RAID group has been generated; and

    directing a DMA (Direct Memory Access) controller to obtain the vertical ECC from a DRAM (Dynamic Random Access Memory) and store the vertical ECC to a buffer when the vertical ECC within the RAID group has been generated, thereby enabling the vertical ECC to be programmed to the storage unit.
