Abstract
Jumboblocks (JBs) having an uncorrectable error correction code (UECC) error are linked to a bad block in a storage address table (SAT) in order to optimize read and write operations. Bad blocks are designated as a bad block during a manufacturing process or associated with a write uncorrectable error. When a JB is identified as having the UECC error, the controller updates a corresponding mapping of the SAT to point to a bad block, where each JB having the UECC error points to the bad block. When a read command is received by the controller for the data of the JB having the UECC error, the controller scans the SAT, determines, from the SAT, that the JB identification points to the bad block, and returns a UECC message to the requester of the data of the JB having the UECC error.
