| Abstract | An apparatus of a memory system and an operating method thereof includes a plurality of memory devices; and a controller coupled to the plurality of memory devices, wherein the controller is configured to perform a symmetric OVS read with at least an initial read threshold, and create a symmetric read result; perform an asymmetric OVS read with at least the initial read threshold, and create an asymmetric read result; adjust the initial read threshold according to at least the symmetric read result and asymmetric read result, and create an optimal read threshold; and execute data recovery process with the optimal read threshold. |
