Abstract
Provided herein may be a memory controller and a memory system including the same. The memory controller includes a scanning period controller configured to reset, whenever scanning points sequentially arrive, access information indicating whether each of a plurality of pages is accessed, and set a scanning interval for each of the pages between the scanning points for the page based on an attribute of the page, an attribute determiner configured to determine, as a hot page or a cold page, the attribute of each of the pages based on an access interval for the page from the first scanning point among the scanning points for the page to time at which access to data stored in the page is requested, and a memory allocator configured to control first and second memory devices based on the attributes of the pages.
