Summary:Systems and methods for improving data refresh in flash memory are described. In one embodiment, the method includes identifying a first garbage collection unit (GCU) of the storage system, computing a parity function in relation to the first GCU, identifying a data impairment in a first block, the first block being from the N blocks in the first GCU, removing the first block from the first GCU after identifying the data impairment in the first block, and recomputing the parity function when the first block is not cloned.
