US Patent 8386722 Stacked DIMM memory interface

One embodiment of the present invention sets forth an interface circuit configured to combine time staggered data bursts returned by multiple memory devices into a larger contiguous data burst. As a result, an accurate timing reference for data transmission that retains the use of data (DQ) and data strobe (DQS) signals in an infrastructure-compatible system while eliminating the cost of the idle cycles required for data bus turnarounds to switch from reading from one memory device to reading from another memory device, or from writing to one memory device to writing to another memory device may be obtained, thereby increasing memory system bandwidth relative to the prior art approaches.
