A method and apparatus for dynamic issuing of memory access instructions. In particular, a specific data access request that is about to be sent to a memory, such as a frame buffer, is dynamically chosen based upon pending requests within a pipeline. It is possible to optimize video data requests by dynamically selecting a memory access request at the time the request is made to the memory. In particular, if it is recognized that the memory about to be accessed will no longer be needed by subsequent memory requests, the request can be changed from a normal access request to an access request with an auto-close option. By using an auto close option, the memory bank being accessed is closed after the access, without issuing a separate memory close instruction.
