摘要
An electronic device including a memory functional block having multiple ranks of memory and a memory controller functional block coupled to the memory. The memory controller includes refresh logic that detects, based on buffered memory accesses for each rank of memory of the ranks of memory, two or more ranks of memory for which a refresh is to be performed during a refresh interval. Based at least in part on one or more properties of buffered memory accesses for the two or more ranks of memory, the refresh logic determines a refresh order for performing refreshes for the two or more ranks of memory during the refresh interval. The memory controller then performs, in the refresh order, refreshes for the two or more ranks of memory during the refresh interval.
