An embodiment of a method for accessing a storage unit of a flash memory, performed by a control unit, is disclosed to include at least the following steps. A transaction is appended to a bad-column table each time a bad column of a block within the storage unit is inspected. It is determined whether a total number of the transactions within the bad-column table is odd when the control unit determines that the last column of the block is a regular column. A transaction is appended to the bad-column table to indicate that the last column of the block is a bad column when the control unit determines that the total number of the transactions within the bad-column table is odd. |
