ABSTRACT:
Off-die termination module for terminating memory module signal lines in a computer memory subsystem, the computer memory subsystem including a memory controller and a DIMM socket, the memory controller coupled to the DIMM socket via a memory module signal line, the off-die termination module including: an off-die termination component configured to terminate the memory module signal line upon activation; and a spring loaded notch pin implemented as part of the DIMM socket, the spring loaded notch pin configured to toggle activation of the off-die termination component in dependence upon presence of a DIMM in the DIMM socket including activating the off-die termination component upon removal of a DIMM from the DIMM socket and deactivating the off-die termination component upon installation of a DIMM in the DIMM socket.
