Abstract
A method of operating a memory module including a plurality of semiconductor memory devices organized into a multi-rank memory on a DIMM and a memory buffer included on the DIMM, operatively coupled to the multi-rank memory, can be provided by mapping an access to the DIMM from a memory controller to semiconductor memory devices included in more than one rank within the multi-rank memory based on a mode register set signal and selectively linking rank control signals during a parallel bit test operation to the more than one rank within the multi-rank memory plurality of semiconductor memory devices.
