DDR2 and DDR3 memory is finding its way into lots of designs these days. Depending on how you are using these technologies in your designs, the technologies present challenges with special topologies and very specific net length or delay matching.
I have a couple of questions for any customers that may be currently using (or planning to use in the future) this type of memory on their designs:
Are you using DDR2 or DDR3; Or possibly both?
Are your designs using onboard memory chips or are you using memory module daughtercards?
Your responses will help us better understand the design challenges you are now facing and help us as we move ahead with better design solutions.
Thanks in advance for all responses!
