I don't even understand all the BS ATI is coming up with ... a dual rank design without latency ...

first of all, the latency is negligible because it is basically the same the the internal bank-to bank latency, second if the chips are put back to back on the PCB, you can do a clam-shell arrangement either like the one shown at the link or with tying addresses AND data together and use one additional chipselect to fake an extra address line and handle the two chips as one single component with two dies and 8 internal banks - which increases the number of open pages and cuts further down on latency.
