A system, method and device for managing power distribution on a shared bus system that interconnects multiple devices each containing a signal termination component are disclosed herein. In one embodiment, the method of the invention includes detecting and communicating thermal indicia of one or more of the devices in the shared bus system to a memory controller device. The memory controller includes an on-die termination control circuit for setting and resetting the enablement of the signal termination components of the one or more devices. In a preferred embodiment, the on-die termination control circuit sets and resets the enablement of the signal termination components in accordance with the determined thermal indicia.
