A Low-Cost Resonance Mitigation Technique for Multidrop Memory Interfaces

A passive resonance mitigation technique is proposed for multidrop memory interfaces. In this method, coupled transmission lines are used to prevent destructive signal resonance caused by signal reflection from the capacitive loads and mismatches in the channel. The proposed idea is verified in a simple experimental setup that roughly models a multi-Dual In-Line Memory Module system, and measurement results are provided.
