Abstract
Disclosed is a storage device which includes non-volatile memory devices, temperature sensors, and a storage controller receiving temperature information from the temperature sensors. Each of the plurality of memory blocks is allocated to one of a plurality of zones, and the storage controller performs a first zone reallocation operation to reallocate a block of a non-volatile memory device with a lower temperature to a zone with a higher hit ratio and to reallocate a block of a non-volatile memory device with a higher temperature to a zone with a lower hit ratio. The storage controller performs a first zone rating to generate a first table based on hit ratio information of the zones, performs a first memory rating to generate a second table based on the temperature information, and performs the first zone reallocation operation based on the first table and the second table.
