Abstract
During data storage device operation, data of multiple blocks of a non-volatile memory device, logically grouped as a jumboblock, may be protected by an exclusive or (XOR) signature, where the XOR signature may be used to recover data of a block of the multiple blocks. During a recovery/relocation operation, data of the jumboblock is read from the non-volatile memory device during the recovery of the lost data and again when the data is relocated. However, because the data read during data storage device operation is temporarily stored in a volatile memory device, the controller utilizes the relevant data stored in the volatile memory device and the data stored in the non-volatile memory device to recover corrupted data. Thus, the amount of reads from the non-volatile memory device decreases due to the relevant data is read from the volatile memory device, which may improve data storage device performance.
