    摘要： The present invention provides a method, apparatus, and system for dynamically changing the sizes of power-control pools that are used to control the power consumption levels of memory devices. In one embodiment, a request to change the sizes of the memory power-control pools is received. In response to receiving the request to change the sizes of the memory power-control pools, the memory devices are placed in a specific operating mode or power state after being refreshed in a periodic refresh cycle. In response to a signal indicating that all memory devices have been placed in the specific operating mode, powercontrol pools are resized according to pool size values corresponding to the request received.

    摘要： Embodiments of the invention are generally directed to systems, methods, and apparatuses for using interface frequency modulation to allow non-terminated operation and power reduction. In some embodiments, an apparatus includes an interface having a termination mode and a power management controller coupled with the interface. The apparatus may also include a power management controller coupled with the interface. In some embodiments, the power management controller is capable of dynamically reducing the operating frequency of the interface and disabling the termination mode to reduce the power consumed by the interface. Other embodiments are described and claimed.

    摘要： One or more memory requests are stored in a request buffer. Each memory request targets a memory device in a memory system having one or more memory devices. Each memory device has a first power state and a second power state. Each memory request is issued in an order from the request buffer to the memory system. The memory device targeted by one memory request from the request buffer is identified prior to or while another memory request ahead of the one memory request is issued to the memory system and performed by the memory system. The identified memory device is placed or maintained in the second power state prior to issuing the one memory request to the memory system.

    摘要： In an embodiment, a memory interface may send an indication that a request is being sent. The indication may be sent to a non-volatile memory via a point-to-point bus between a memory interface and the non-volatile memory. The memory interface may send the request to the non-volatile memory via the bus. The request may include an address that may be used to identify a location for storing or reading data. The non-volatile memory may acquire the request from the bus and process the request. After processing the request, the non-volatile memory may send an indication to the memory interface that indicates the non-volatile memory has a response to send to the memory interface. The memory interface may grant access to the bus to the non-volatile memory. After being granted access to the bus, the non-volatile memory may send the response to the memory interface.
