Abstract
A memory controller for controlling data access to a memory comprises a refresh controller. A read count memory part included in the refresh controller counts the number of read operations on each page of the memory and stores the read count therein. If the read count for any page exceeds a predetermined number, the refresh controller rewrites data stored in this page into the memory.
