Abstract
A method and system which will provide data processing systems having memory controllers with the ability to intelligently schedule accesses to system memory. The method and system provide a memory controller having a page-state sensitive memory arbiter. The method and system further include one or more memory state tracking units operably coupled to the page-state sensitive memory arbiter, and the one or more memory state tracking units operably coupled to a system memory. The one or more memory state tracking units operably coupled to a system memory further include the one or more memory state tracking units operably coupled to one or more system memory devices. The method and system track system memory status, monitor pending memory access requests, and schedule one or more pending memory access requests for execution dependent upon the system memory status and the pending memory access requests.
