Disclosed is a storage device, the device comprising, a nonvolatile memory device configured to store data; and a storage controller configured to perform logging for a selected memory area of the nonvolatile memory device in response to a specific event based on receiving a telemetry request from a host, and transmit log data collected by the logging in response to the telemetry request, the storage controller including a logging module configured to sample distribution data of a voltage range corresponding to the event type during the logging and provide the sampled distribution data as the log data.

Storage device, storage system and logging method thereof

Provided are a memory controller, a method of operating the memory controller, and a storage device including the memory controller. The method includes performing a first operation on a non-volatile memory; storing a first code path corresponding to pieces of codes executed as the first operation is performed in a history buffer; comparing the first code path with a plurality of reference code paths related to the first operation; and identifying whether the first operation is abnormally performed based on a result of the comparison.
