    摘要: 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.

    摘要: One embodiment of the present invention sets forth an abstracted memory subsystem comprising abstracted memories, which each may be configured to present memory-related characteristics onto a memory system interface. The characteristics can be presented on the memory system interface via logic signals or protocol exchanges, and the characteristics may include any one or more of, an address space, a protocol, a memory type, a power management rule, a number of pipeline stages, a number of banks, a mapping to physical banks, a number of ranks, a timing characteristic, an address decoding option, a bus turnaround time parameter, an additional signal assertion, a sub-rank, a number of planes, or other memory-related characteristics. Some embodiments include an intelligent register device and/or, an intelligent buffer device. One advantage of the disclosed subsystem is that memory performance may be optimized regardless of the specific protocols used by the underlying memory hardware devices.
