1. A method of operating a storage device including a storage controller and a plurality of nonvolatile memories, each of the plurality of nonvolatile memories including a temperature sensor, the method comprising:
performing a first operation on the plurality of nonvolatile memories using a plurality of driving parameters required for the first operation, wherein the plurality of driving parameters include a first driving parameter;
transmitting, by the storage controller, a command for temperature check to the plurality of nonvolatile memories;
transmitting, by at least one of the plurality of nonvolatile memories, temperature information of the at least one of the plurality of nonvolatile memories to the storage controller, the temperature information being obtained using the temperature sensor;
obtaining standing time information of each of the plurality of nonvolatile memories by applying a temperature acceleration condition based on the temperature information; and
changing a value of the first driving parameter based on at least one of the temperature information and the standing time information.
