Abstract
An embodiment of a method for accessing a storage unit of a flash memory, performed by a processing unit, includes at least the following steps. After all messages within a RAID (Redundant Array of Independent Disk) group are programmed, it is determined whether a vertical ECC (Error Correction Code) within the RAID group has been generated. The processing unit directs 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.
