Abstract:
A method and system for accessing a dynamic random access memory (DRAM) is provided. A memory controller includes a content addressable memory (CAM) based decision control module for determining a next best access request for the DRAM. The CAM based decision control module includes a CAM access storage module for storing access requests, a next access table module for storing the next best access request, and a decision logic module for determining the next best access request based on results from the CAM access storage module and the next access table module. Further, the memory controller includes a DRAM access control interface for implementing signaling required to access the DRAM. The method includes storing access requests in a CAM access storage module. The method includes determining which of the stored access requests is a next best access request. Further, the method includes processing the next best access request.
