Disabling Unused System Memory Outputs

Any system memory (SM) interface signal that goes to a memory in which it is not connected to any actual memory devices (such as SoDIMM connector is unpopulated, or is single-sided) is tri-stated. The benefits of disabling unused SM signals are:

  • Reduced leakage power consumption.
  • Reduce unintended receiver operation due to unterminated transmission lines.

  • When a given rank is not populated, the corresponding control signals (CLK_​DP/CLK_​DN/CKE/ODT/CS) are not driven.
