Storage device initializing e-fuse region, and method of operating the same

An operating method of a storage controller which communicates with a non-volatile memory device, the method comprising,

• providing the non-volatile memory device with a first command indicating a target memory operation of user data in a memory region of the non-volatile memory device;
• receiving a first response indicating a failure of the target memory operation, from the non-volatile memory device;
• providing the non-volatile memory device with a second command indicating initialization of an E-fuse region of the non-volatile memory device based on the first response;
• and
• receiving a second response indicating that the E-fuse region is updated, from the non-volatile memory device.

A storage device comprising:

• a storage controller;
• and
• a non-volatile memory device,
• wherein the storage controller is configured to provide the non-volatile memory device with a first command indicating a target memory operation of user data,
• wherein the non-volatile memory device includes a memory region and an E-fuse region and is configured to perform the target memory operation in the memory region based on first setting information stored in the E-fuse region,
• wherein the storage controller is further configured to:
• receive a first response indicating a failure of the target memory operation, from the non-volatile memory device;
• and
• provide the non-volatile memory device with a second command indicating an initialization operation of the E-fuse region based on the first response, and
• wherein the non-volatile memory device is further configured to:
• update the first setting information of the E-fuse region based on the second command, so as to be changed to second setting information;
• and
• provide the storage controller with a second response indicating that the E-fuse region is updated.
