Abstract
Disclosed is a storage controller which includes a history table and communicates with a non-volatile memory device. A method of operating the storage controller includes determining whether history data of a target memory block are registered at the history table, providing a history read request for the target memory block based on the history data when it is determined that the history data are registered, receiving first raw data corresponding to the history read request from the non-volatile memory device, generating skew information of the target memory block based on the first raw data and the history data, and determining whether to perform a read reclaim operation of the target memory block, based on the skew information.
