摘要:
Examples are given for generating or providing a moving read reference (MRR) table for recovering from a read error of non-volatile memory included in a storage device. In some examples, priorities may be adaptively assigned to entries included in the MRR table. The entries may be ordered for use based on the assigned priorities. In other examples, the MRR table may be ordered for use such that entries with a single MRR value for each read reference value may be used first over entries having multiple MRR values for each read reference value. For these other examples, the MRR table may be adaptively reordered based on which entries were successful or unsuccessful in recovering from a read error but may still be arranged to have single MRR value entries used first for use to recover from another read error.
