摘要： Embodiments help dynamically configure the width of PCIe links and also determine how to best configure the appropriate link width. This helps avoid situations where PCIe links are almost always active even at very low traffic rates. Embodiments achieve these benefits based on, for example, run-time monitoring of bandwidth requirement for integrated and non-integrated ports located downstream for the PCIe controller. This provides power savings with little impact on performance. Other embodiments are discussed herein.

摘要： Embodiments of the invention supply power to DRAM or other memory devices with a multi-phase voltage regulator. A power controller coupled to the multi-phase voltage regulator causes one or more phases of the multi-phase voltage regulator to be activated or deactivated (shed) according to predetermined criteria. Embodiments of the invention thus improve power management by providing one or more reduced power states for the memory devices. Other embodiments are described.

摘要： Embodiments of the invention are generally directed to systems, methods, and apparatuses for rank coordination. In some embodiments, a host includes rank coordination logic. The rank coordination logic may include performance measurement logic to measure a performance of a memory channel and dwell period control logic to select a length of a dwell period based, at least in part, on the performance of the memory channel. Other embodiments are described and claimed.

摘要： Embodiments of the invention are generally directed to systems, methods, and apparatuses for clock enable (CKE) coordination. In some embodiments, a memory controller includes logic to predict whether a scheduled request will be issued to a rank. The memory controller may also include logic to predict whether a scheduled request will not be issued to the rank. In some embodiments, the clock enable (CKE) is asserted or de-asserted to a rank based, at least in part, on the predictions. Other embodiments are described and claimed.
