Control of page access in memory

摘要

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.

主权项

1. A method of controlling access to a memory bank in a memory array, comprising:
receiving a first request for accessing a first page in the memory bank from a first master component, wherein the memory bank comprises a plurality of pages; in response to the first request, opening the first page in the memory bank with a controller; receiving a second request for accessing a second page in the memory bank from a second master component; and in response to the second request, opening the second page with the controller such that the first page and the second page are concurrently open.
