Abstract: A read retry table generator is coupled to a plurality of memory dies via a data path. The read retry table generator is configured to: collect data from a plurality of memory cells coupled to a plurality of word lines in the plurality of memory dies; determine a pass rate of collected data appertaining to a plurality of clusters; select a cluster candidate among the plurality of clusters, based on a pass rate of collected data; and cluster the collected data into the cluster candidate to generate a read retry table.

Abstract: A read pattern obtained in a read operation for determining an optimal read voltage when an initial read operation fails is stored, and is used in a read operation to be subsequently performed for determining a new optimal read voltage.
