A first port on the first hub device is in communication with the memory controller via the memory bus, a second port on the first hub device is in communication with a first set of memory devices, and a third port on the first hub device is cascade connected to a first port on the second hub device. A second port on the second hub device is in communication with a second set of memory devices and a third port on the second hub device supports a cascaded connection to a subsequent hub device in the memory system.

摘要： A memory system, having indeterminate read data latency, that includes a memory controller and one or more hub devices. The memory controller is configured for receiving data transfers via an upstream channel and for determining whether all or a subset of the data transfers include a data frame by detecting a frame start indicator. The data frame includes an identification tag that is utilized by the memory controller to associate the data frame with a corresponding read instruction issued by the memory controller. The one or more hub devices are in communication with the memory controller in a cascade interconnect manner via the upstream channel and a downstream channel. Each hub device is configured for receiving the data transfers via the upstream channel or the downstream channel and for determining whether all or a subset of the data transfers include a data frame by detecting the frame start indicator.

摘要： A method for providing frame start indication that includes receiving a data transfer via a channel in a memory system. The receiving is in response to a request, and at an indeterminate time relative to the request. It is determined whether the data transfer includes a frame start indicator. The data transfer and “n” subsequent data transfers are captured in response to determining that the data transfer includes a frame start indicator. The data transfer and the “n” subsequent data transfers make up a data frame, where “n” is greater than zero.

摘要： A method and system for providing identification tags in a memory system having indeterminate data response times. An exemplary embodiment includes a memory controller in a memory system. The memory controller includes a mechanism for receiving data packets via an upstream channel, the data packets including upstream identification tags. The memory controller also includes a mechanism having instructions for facilitating determining if a received data packet is in response to a request from the memory controller. Input to the determining includes an upstream identification tag included in the received data packet. If the received data packet is determined to be in response to a request from the memory controller, then the received data packet is matched to the request, thereby allowing the memory controller to operate with indeterminate data response times.

摘要： A method for providing indeterminate read data latency in a memory system. The method includes determining if a local data packet has been received and storing it into a buffer device. The method also includes determining if the buffer device contains a data packet and determining if an upstream driver for transmitting data packets to a memory controller via an upstream channel is idle, and in response thereto the data packet is transmitted to the upstream driver. The method further includes determining if an upstream data packet has been received and the upstream driver is not idle, then the upstream data packet is stored into the buffer device. The upstream data packet is selectively transmitted to the upstream driver. If the upstream driver is not idle, then any data packets in progress are continued being transmitted to the upstream driver.
