[SI-LIST] Re: DDR SDRAM

Hi Bob,
I am involved in a similar situation. I have not run across a lot of info on SI 
or timing issues, however, on the Micron site there is a "designer's toolkit" 
that offers some things that help. I found that the power calculator tool is 
quite handy.
Additionally, the DDR spec and addendum are mostly concerned with the timing 
diagrams and pin-outs for the 4/8/16 bit wide devices. You may be able to find 
more info if you look into the SDRAM stuff, since the DDR is SDRAM with data 
registered on both
edges of the clock. 

Let me know if you find anything additional. It would be helpful.

Regards,
Peter
