What is DDR2 & DDR3 PCB Integrity Design about?

This document discusses PCB design considerations for DDR2 and DDR3 memory, focusing on signal and power integrity, especially for 4-layer PCBs. It covers topics like PCB stackup and impedance matching, interconnection topology, and delay matching. DDR2 requires 50 ohm single-ended and 100 ohm differential impedance matching, while DDR3 allows 40-60 ohms for addresses and commands. PCB layer count and impedance matching affect signal integrity, and design tools can simulate these factors.
