Distributed Termination for Flyby Memory Buses

摘要

Methods and systems that perform distributed termination for shared signal buses on memory modules. Distributed termination improves signal quality and results in higher overall memory performance. Distributed termination enables depopulation of devices on branches without significant performance degradation. Distributed termination enables new signal topologies that may enable higher performance.

1. A computer memory module comprising:
a shared input configured to receive an input signal; a bus connected to the shared input; and a plurality of memory devices connected via stubs to the bus, wherein the plurality of memory devices are configured to allow the input signal to propagate through the memory devices, wherein each of at least a portion of the memory devices comprise:
a resistive element having a first end connected to the stub; anda second end connected to a termination voltage.
