Abstract

In one form, a data processing system includes a host integrated circuit having a memory controller, a memory bus coupled to the memory controller, and a memory module. The memory module includes a bulk memory and a memory module scratchpad coupled to the bulk memory, wherein the memory module scratchpad has a lower access overhead than the bulk memory. The memory controller selectively provides predetermined commands over the memory bus to cause the memory module to copy data between the bulk memory and the memory module scratchpad without conducting data on the memory bus in response to a data movement decision.
