摘要:
Methods and systems for decoding raw data may select a preliminary read-level voltage from a sequence of read-level voltages based on a decoding success indicator and execute a preliminary hard decoding operation to decode raw data read from a plurality of memory cells using the preliminary read-level voltage. If the preliminary hard decoding operation is successful, the decoded data from the hard decoding operation is returned. If the preliminary hard decoding operation is unsuccessful, a multi-stage decoding operation may be executed to decode raw data read from the plurality of memory cells using the sequence of read-level voltages, and returning decoded data from the multi-stage decoding operation upon completion of the multi-stage decoding operation. The decoding success indicator is maintained based on results of the preliminary hard decoding operation or the multi-stage decoding operation.
