Abstract: Disclosed is an operating method of a storage device which includes a non-volatile memory device and a storage controller. The method includes providing, by the storage controller, the non-volatile memory device with a first command indicating a target memory operation of user data, performing, by the non-volatile memory device, the target memory operation in a memory region based on the first command and first setting information stored in an E-fuse region, providing, by the non-volatile memory device, the storage controller with a first response indicating that the target memory operation fails, providing, by the storage controller, the non-volatile memory device with a second command indicating an initialization operation of the E-fuse region based on the first response, updating, by the non-volatile memory device, the first setting information of the E-fuse region based on the second command, so as to be changed to second setting information.
