Abstract
Multiple reads of memory cells of a flash memory device are initiated at different read levels to obtain raw data. For each different read level, multiple decoding operations are initiated to decode the raw data, each decoding operation using a different one of a plurality of sets of decoding information associated with the different read level. Decoding success rates are determined for one or more of the plurality of sets based on the one or more of the plurality of sets being used to successfully decode data and, for each different read level, an order of the plurality of sets is determined based on the determined success rates. A selected set of decoding information is selected for use in decoding raw data obtained from a read performed at a respective read level based on the respective read level and the set order of the plurality of sets for the respective read level.
