Abstract
The present techniques provide systems and methods of controlling access to more than one open page in a memory component, such as a memory bank. Several components may request access to the memory banks. A controller can receive the requests and open or close the pages in the memory bank in response to the requests. In some embodiments, the controller assigns priority to some components requesting access, and assigns a specific page in a memory bank to the priority component. Further, additional available pages in the same memory bank may also be opened by other priority components, or by components with lower priorities. The controller may conserve power, or may increase the efficiency of processing transactions between components and the memory bank by closing pages after time outs, after transactions are complete, or in response to a number of requests received by masters.
