        DDR, DDR2 and DDR3 memory reference layouts can be found on <a href="http://www.jedec.org/standards-documents/technology-focus-areas/memory-module-design-file-registrations">JEDEC website</a>. They provide schematics and PCB brd files (requires registration). It’s very useful to see how JEDEC does the layout.
