The invention provides a method for hierarchy management for a hybrid automatic repeat request (HARQ) memory, wherein, the HARQ memory includes an on-chip memory including one or more storage blocks, each of which corresponds to a using status bit for indicating whether the storage block is overwriteable. The method includes the following steps of: when receiving new data of a coded block, searching the on-chip memory for any overwriteable storage block, and if there exists an overwriteable storage block, storing the new data of the coded block into the storage block and setting the using status bit corresponding to the storage block to be un-overwriteable; if there is no overwriteable storage block, storing the new data of the coded block into an off-chip memory; and when the new data of the coded block are checked and pass the check, setting the using status bit corresponding to the storage block in which the new data of the coded block are stored to be overwriteable. The invention also provides a corresponding system. The scheme disclosed in the invention reduces power consumption. |
