    摘要: A method and system for extending tTR range of memory devices coupled to a memory devices is described. A first group of memory devices and a second group of memory devices are identified. The first group includes memory devices located close to a memory controller and the second group includes memory devices located a distance away from the memory controller. Commands to access memory devices in the first and second groups are sent. A command to the first group is sent with a transitional delay when the command to the first group follows a command to the second group. In response to the commands, data from the first and second groups is received.

    摘要: According to one embodiment, the present invention discloses a method of managing power in a memory system. The memory system includes a plurality of memory devices. Each one of the memory devices is grouped in a first group or a second group. First, access to a memory device is requested. It is next determined whether the requested memory device is located in the first group. If the requested memory device is not located within the first group, it is determined whether the first group is filled to capacity. If the first group is not filled to capacity, the requested memory device is transferred to the first group. According to a further embodiment, each one of the memory devices grouped into the first group is further grouped in to a first subgroup or a second subgroup.

    摘要: One embodiment of the invention is a method for decoding a memory access address. A portion of the memory access address is compared to a plurality of boundary values, each of the plurality of boundary values representing an uppermost address for a group of memory devices, each of the memory devices in the group having the same configuration. A group number is generated that represents an addressed group that contains an addressed memory device that contains the memory access address. A device number is generated that represents the location of the addressed memory device within the addressed group. A device selection signal is generated responsive to the group number and the device number.

    摘要: A memory repeater hub comprising a main memory channel interface circuit, an expansion control channel interface circuit, and an expansion memory channel interface circuit. The main memory channel interface circuit receives a memory control packet and a memory data packet from a main memory channel. The expansion control channel interface circuit receives a first expansion control packet and a second expansion control packet from an expansion control channel. The expansion memory channel interface circuit selectively transmits the memory control packet to an expansion memory channel responsive to the first expansion control packet, and selectively transmits the memory data packet to the expansion memory channel responsive to the second expansion control packet.
