Hi,
I am working on DDR3 8 Rank (DIMM), for this i want to do termination on
Data signals using ODT option,
As per my knowledge only 1 Rank can be accessed by the controller
(Motherboard controller) at a time.
When controller is writing to a single Rank (Either Read or Write) that
particular Rank device ODT's should be enabled but what should be the ODT
conditions on other Ranks ( It has to be anabled or disabled or Terminatted
ot RTT, nom or Terminated to RTT, WR)?
Could somebody help me in also understanding how the multirank DIMM's are
accessed by the controller along with the ODT options.
Regards,
S Shankar
