1. A storage device comprising:
a memory including a plurality of memory blocks; and
a controller configured to:
determine a candidate memory block, accessed among the plurality of memory blocks when the temperature of the memory is equal to or higher than a first temperature, as a target memory block based on a number of times the candidate memory block is accessed in a state in which the temperature of the memory is equal to or higher than the first temperature, and
determine, using the target memory block, whether to apply a thermal throttling mode to a target operation to be executed on the memory when the temperature of the memory is equal or higher than a second temperature.
