Abstract:
1. A method comprising: generating an error bit checksum to cover transmission errors for a plurality of data bits over a plurality of User Interval (UI) in length; framing the plurality of data bits in a write data frame, wherein the write data frame is a first multiple of the UI in length; transferring the write data frame to a dynamic random access memory (DRAM) device via one or more lanes of a data interconnect; framing the error bit checksum in a write error bit frame, wherein the write error bit frame is a second multiple of the UI in length; and transferring the write error bit frame to the DRAM device via the one or more lanes of the data interconnect, wherein only a subset of the plurality of UI in length are used to transfer the write error bit frame to the DRAM device in which some of the UI contain the write error bit frame and in which at least some of the UI do not contain the write error bit frame.
