Abstract:
A storage device includes a memory storage region and a controller having a processor. The processor retrieves user data from the memory storage region using a physical block address corresponding to a logical block address (LBA), in response to a read command. The retrieved user data includes a first hash received through a host interface in a prior host data transmission. The processor further performs error correction on the user data to generate error-corrected user data. The processor further causes a cryptographic engine to produce a second hash of the error-corrected user data. The first hash is compared to the second hash associated with the error-corrected user data to determine a match result. A notification is generated in response to the match result.
