Abstract

A memory device of a storage device may perform a test read of the memory device for each entry of a set of entries of an in-memory history read retry (HRR) table using a set of read thresholds corresponding to that entry. The memory device may identify an entry in the set of entries having a lowest failed bit count (FBC) obtained from the test read of each entry, and update the in-memory HRR table to have the identified entry with the lowest FBC be at a beginning of the in-memory HRR table. The memory device may also notify a memory controller coupled to the memory device to update an in-controller HRR table stored in the memory controller based on the update to the in-memory HRR table.
