STORAGE CONTROLLER RECEIVING READ DATA AND DISTRIBUTION INFORMATION, METHOD OF OPERATING THE SAME, AND METHOD OF OPERATING STORAGE DEVICE INCLUDING THE SAME

Disclosed is a method of operating a storage controller which communicates with a non-volatile memory device. The method includes providing a read command to the non-volatile memory device, receiving first read data and first distribution information corresponding to the read command from the non-volatile memory device, determining whether an error of the first read data is uncorrectable, and updating offset information of a history table in the storage controller based on the first distribution information, in response to determining that the error of the first read data is correctable.
