Time and frequency domain memory channel characterization and correlation methodology

First, this paper discusses a robust and efficient de- embedding technique that can be used for TDR-PNA- simulation correlation in time or frequency domain. Employing the de-embedding technique, TDR-PNA was shown to correlate very well with 2 mV resolution in time- domain, when TDR repeatability is 2 mV. Next, a systematic analysis of memory channel TDR-simulation correlation was detailed. Time domain correlation served as an efficient and straightforward way of capturing impedance discontinuities and crosstalk level. Finally, some design, modeling, and measurement guidelines for platform memory interconnect development were recommended.
