ABSTRACT:
Systems and methods for providing dynamic memory pre-fetch. Embodiments include a hub device including an input command stream interface and an adaptive pre-fetch logical unit (APLU). The input command stream interface detects commands from a memory controller directed to one or more memory devices that are connected to the hub device. The APLU independently analyzes the commands to determine access patterns to the memory devices. The APLU also dynamically selects between enabling a pre-fetch function and disabling the pre-fetch function for the memory devices based on the results of the analysis.
