Abstract
A memory system includes a plurality of memory device ranks. A memory controller having a connection with the plurality of memory device ranks is adapted to obtain command information being issued to one of the plurality of memory device ranks. The memory controller is also adapted to generate a power weight value based on a command type from the command information. The memory controller increments a power count of the one of the plurality of memory device ranks by the power weight value generated. The memory controller then compares the power count of the one of the plurality of memory device ranks to a threshold value set for the one of the plurality of memory device ranks. If it is determined that the power count exceeds the threshold value, the memory controller is adapted to throttle the one of the plurality of memory device ranks.
