Systems and methods for providing a dynamic memory buffer bank policy. Embodiments include a hub device for selecting a bank page policy. The hub device includes an input command stream interface and a bank page policy module. The input command stream interface detects commands from a memory controller that are directed to one or more memory devices that are connected to the hub device. The bank page policy module independently analyzes the commands to determine access patterns to the memory devices and for dynamically selecting between an open bank page policy and a closed bank page policy for the memory devices based on the analysis.
