Dual rank connection of DDR3 with P1021

Hi,

I need to use the Dual rank of the System to support 2GB. For initial stage we are going to use only 1GB, if required we need to use the 2GB configuration.  So, For the initial stage we will use the rank1 alone and for late we will use the dual rank system. I have attached the block level connection diagram of my system,Can you verify my configuration is correct or not? Kindly reply ASAP.

PFA

Thanks in Advance!

Your configuration is basically correct. Note however that we recommend to use VTT termination on the address/command/control signals.
