摘要:
The key limiter in a multi-drop system, such as a multi-drop memory system, is the super-positioning of reflection noise from multiple modules or pluggable units, such as DIMMs. Using the noise cancellation approach of the present invention, the noise is distributed across the width of the pulse thus significantly reducing the impact of noise super-positioning. Use of the system of the present invention provides improved noise margins and is a key enabler of high performance, high speed bus, particularly at higher bit rates, as well as an enabler for higher capacity modules, such as DIMMs. The system provides for electrical traces from each of the modules of varying lengths thereby distributing the noise reflections.
