<p>PURPOSE: A memory system and a refresh control method are provided to improve the performance of the memory system by performing a refresh operation according to refresh property information. CONSTITUTION: A semiconductor memory device(100) includes a plurality of memory cells. A memory controller(200) generates a special command to search refresh property information stored in the semiconductor memory device and controls the refresh operation of the semiconductor memory device. The semiconductor memory device outputs the refresh property information to the memory controller in response to the special command generated from the memory controller.</p> |
