1. An operating method of a storage controller configured to communicate with a host and with a non-volatile memory device, the method comprising:
generating an error count by counting a number of first-type error bits of a target super block of the non-volatile memory device;
determining whether the error count exceeds a first reference value;
fetching setting data from a latch unit of the non-volatile memory device to provide fetched setting data when the error count exceeds the first reference value;
determining whether reference setting data of a setting table are matched with the fetched setting data, the reference setting data indicating information about a designed operating environment of the non-volatile memory device; and
providing a reset request to the latch unit when the reference setting data does not match the fetched setting data,
wherein determining whether the reference setting data of the setting table are matched with the fetched setting data includes determining whether an indicated major portion of the reference setting data matches a portion of the fetched setting data corresponding to the indicated major portion of the reference setting data.
