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.
1. A memory system having indeterminate read data latency, the memory system comprising: a memory controller configured for: receiving data transfers via an upstream channel; anddetermining whether all or a subset of the data transfers comprise a data frame by detecting a frame start indicator, wher
1. A memory system having indeterminate read data latency, the memory system comprising: a memory controller configured for: receiving data transfers via an upstream channel; anddetermining whether all or a subset of the data transfers comprise a data frame by detecting a frame start indicator, wherein 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; andone or more hub devices in communication with the memory controller in a cascade interconnect manner via the upstream channel and a downstream channel, each hub device configured for: receiving the data transfers via the upstream channel or the downstream channel; anddetermining whether all or a subset of the data transfers comprise a data frame by detecting the frame start indicator. 2. The memory system of claim 1 wherein one or more of the hub devices include memory devices and a mechanism for processing the read instruction when it is directed to one of the memory devices, the processing including creating a data frame having the frame start indicator. 3. The memory system of claim 1 wherein the memory controller is further configured for generating read data instructions and transmitting the read data instructions to one or more of the hub devices via the downstream channel. 4. A memory system having indeterminate read data latency, the memory system comprising: a memory controller configured for: receiving data transfers via an upstream channel in a channel that includes the upstream channel and a downstream channel;determining that a data transfer includes a frame start indicator;capturing the data transfer and “n” subsequent data transfers in response to determining that the data transfer includes the frame start indicator, the data transfer and the “n” subsequent data transfers comprising a data frame, where “n” is greater than zero, and the data frame includes an identification tag; andassociating the data frame with a corresponding read instruction issued by the memory controller, the associating based on the identification tag; anda hub device in communication with the memory controller via the channel, the hub device configured for: receiving the data transfers via the channel; anddetermining whether all or a subset of the data transfers comprise a data frame by detecting the frame start indicator. 5. The memory system of claim 4 wherein the hub device includes memory devices and a mechanism configured for processing the read instruction when it is directed to one of the memory devices, the processing including creating a data frame having the frame start indicator. 6. The memory system of claim 4 wherein the memory controller is further configured for generating the read data instruction and transmitting the read data instruction to the hub device via the downstream channel. 7. The memory system of claim 4 wherein the determining that the data transfer includes a frame start indicator includes checking a bit position in the data transfer for a frame start indicator value. 8. The memory system of claim 4 wherein the determining that the data transfer includes a frame start indicator includes checking a plurality of bit positions in the data transfer for a frame start indicator value. 9. The memory system of claim 4 wherein a parity bit in the data transfer is used to validate the determining that the data transfer includes a frame start indicator.
