ABSTRACT:
Techniques for increasing bandwidth in port-per-module memory systems having mismatched memory modules are disclosed. In one particular exemplary embodiment, the techniques may be realized through a memory system comprising a memory module and a memory controller. The memory module comprises a memory component with a memory core for storing data therein. The memory controller comprises a first set of interface connections that provides access to the memory module, a second set of interface connections that provides access to the memory module, and memory access circuitry that provides memory access signals to the memoory module for selecting between a first mode wherein first and second portions of the memory core are accessible through the first and second sets of interface connections, respectively, and a second mode wherein both the first and second pertions of the memory core are accessible through the first set of interface connections.
