Method of operating storage device, storage device performing the same and storage system including the same

A storage system comprising:

• a host;
• and
• a storage device accessed by the host and including a plurality of nonvolatile memories and a storage controller, each of the plurality of nonvolatile memories including a temperature sensor, the storage controller configured to control operations of the plurality of nonvolatile memories,
• wherein the storage controller is configured to check whether a predetermined temperature check cycle for the plurality of nonvolatile memories has been reached, to monitor, in response to a checking result of whether the predetermined temperature check cycle has been reached, temperature information of at least one of the plurality of nonvolatile memories using the temperature sensor, to obtain standing time information of each of the plurality of nonvolatile memories by applying a temperature acceleration condition based on the monitored temperature information, and to change at least one of a plurality of driving parameters required for operating each of the plurality of nonvolatile memories based on at least one of the monitored temperature information and the obtained standing time information.
