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.
1. A method for providing frame start indication, the method comprising: receiving a data transfer via a channel in a memory system, the receiving in response to a request, and the receiving at an indeterminate time relative to the request;determining whether the data transfer includes a frame start
1. A method for providing frame start indication, the method comprising: receiving a data transfer via a channel in a memory system, the receiving in response to a request, and the receiving at an indeterminate time relative to the request;determining whether the data transfer includes a frame start indicator; andcapturing the data transfer and “n” subsequent data transfers in response to determining that the data transfer includes a frame start indicator, the data transfer and the “n” subsequent data transfers comprising a data frame, wherein “n” is greater than zero and the data frame includes a read data identification tag;associating the data frame with its corresponding read instruction based on the read identification tag. 2. The method of claim 1, wherein the corresponding read instruction was issued by a memory controller. 3. The method of claim 1, wherein the receiving, determining and capturing are performed by a memory controller. 4. The method of claim 1 wherein the determining includes checking a bit position in the data transfer for a frame start indicator value. 5. The method of claim 1 wherein the determining includes checking a plurality of bit positions in the data transfer for a frame start indicator value. 6. The method of claim 1 wherein the determining includes checking a bit position in the data transfer and at least one bit position in one or more of the subsequent data transfers for frame start indicator values and capturing the data transfer and “n” subsequent data transfers in response to determining that the data transfer and the one or more subsequent data transfers include the frame start indicator values. 7. The method of claim 1 wherein a parity bit in the data transfer is utilized to validate the determining that the data transfer includes a frame start indicator. 8. A memory controller comprising: a mechanism configured for receiving a data transfer via a channel in a memory system and for determining whether the data transfer includes a frame start indicator, the receiving in response to a request, and the receiving at an indeterminate time relative to the request;a mechanism configured for 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, the data frame including a read data identification tag, and “n” is greater than zero;a mechanism configured for associating the data frame with its corresponding read instruction issued by the memory controller using the read data identification tag; anda mechanism configured for generating read data instructions and for transmitting the read data instructions to one or more downstream devices via the channel. 9. The memory controller of claim 8 wherein the data frame is a requested data frame. 10. The memory controller of claim 8 wherein the data frame is an un-requested data frame.
