US Patent 10175892 Adaptive read algorithm for a nonvolatile medium

An adaptive read algorithm for accessing information stored on a nonvolatile medium. The nonvolatile medium can be organized as a plurality of storage units. A method of servicing a read request to the nonvolatile medium can include recording a history of read-retries for read requests to individual storage units of the nonvolatile medium. The method can include adapting a read algorithm for a read request to a particular storage unit based on the history of the read-retries for the read requests to the individual storage units of the nonvolatile medium.
