Abstract
A memory controller performs an error recovery operation. The controller performs a read operation on a select block using a select read level; decodes data associated with the read operation to generate a syndrome value; determines whether to stop, before a maximum number of iterations, the read operation and the decoding at the select read level, using the syndrome value; when it is determined to stop the read operation and the decoding at the select read level, selects a next read level in a sequence of read levels; and uses the next read level for a subsequent read operation.
