A memory module including first and second ranks is provided. Each rank includes a separate plurality of individually accessible memory locations. Also included in the memory module is a control circuit coupled with the first rank and the second rank. The control circuit is configured to receive a write command for writing data to the first rank, and to process the write command to write the data to both the first rank and the second rank. Another embodiment of the invention features the control circuit alone.
