Dear All, I've never worked on a DDR SDRAM system before. While I have the manufacturer's data sheet, I am seeking general references, especially a generic timing diagram for write and read cycles. Is there some sort of industry standard that governs these modules? If anyone could send me reference(s) or point me to them on the internet, it would be greatly appreciated. Consultants, *please* do not write offering me your services. Once armed with with the requested information, I suspect that we can do this ourselves. Thank you all for your assistance.
