Abstract: Methods, systems, and devices for sorting retired blocks of non-volatile memory cells are described. A memory system may recover a block that has been marked as “bad” using a requalification process. For example, after operating in an error protection mode for the block, the memory system may monitor the block to determine whether a status flag indicating an access error is set. If the status flag is set, the memory system may store information that indicates the block is unrecoverable, and the block may subsequently be retired. Alternatively, if a status flag is not set, the memory system may store information that indicates the block may be recoverable. If one or more additional access operations to the block are successful, the memory system may store information that indicates the block may be used for subsequent access operations.
