    Abstract: Embodiments provide a scheme for determining the order of read threshold voltages used in a read error recovery operation for a memory system. A controller performs one or more read operations on a memory device using one or more read voltages among a plurality of read voltages in a set order. The controller detects a successful read operation among the one or more read operations. The controller determines one or more credits for the one or more read voltages, respectively, in response to the detected successful read operation. The controller updates the set order based on the determined credits.
