Abstract
Memory controllers, systems, methods, and computer-readable mediums for applying a page management policy(ies) based on stream transaction information are disclosed. In one embodiment, a memory controller is provided and configured to receive memory access requests for stream transactions. The memory controller is configured to perform a memory access to a memory page(s) in memory included in the stream transaction. The controller is further configured to apply a page management policy(ies) to the memory page(s) in memory based on information related to the stream transactions. In this manner, the page management policy(ies) can be configured to utilize page open policies for efficiency that stream transactions may facilitate, but while also recognizing and taking into consideration in the page management policy latency issues that can arise when the memory controller is handling memory access requests from different devices.
