Abstract
Disclosed is a method of operating a storage controller which communicates with a non-volatile memory device. The method includes outputting a first command including a request for on-chip valley search (OVS) count data of a memory region of the non-volatile memory device to the non-volatile memory device, wherein the OVS count data include a first count value of a first read voltage and a second count value of a second read voltage, receiving the OVS count data from the non-volatile memory device, determining a first error count value for the first read voltage and a second error count value for the second read voltage, based on the OVS count data, and determining a subsequent operation, based on the first and second error count values.
