Abstract
A memory system for controlling memory refresh is provided. An embodiment of the memory system includes a memory configured to operate in a self-refresh mode and an auto-refresh mode, the memory having a plurality of memory locations, and a memory controller configured to access a first one of the memory locations while a second one of the memory locations is being refreshed in the auto-refresh mode. Another embodiment of the memory system includes a memory that can communicate its self refresh address to the memory controller. A further embodiment includes a memory controller that can communicate an auto-refresh address to a memory.
