System and method for providing a back door communication path between channels on dual-channel DIMMs

A method of providing a dual-channel Dual In-Line Memory Module (DIMM), the method comprising:

• providing a first bank of Dynamic Random Access Memory (DRAM) devices of the dual-channel DIMM, the first bank of DRAM devices to conduct a first memory transaction on a first memory channel of a memory controller of an information handling system;
• providing a second bank of DRAM devices of the dual-channel DIMM, the second bank of DRAM devices to conduct a second memory transaction on a second memory channel of the memory controller;
• and
• providing a plurality of back door communication paths, each back door communication path being between a first data bit of the first bank of DRAM devices and a second data bit of the second bank of DRAM devices, the first data bit corresponding to a particular address on the first memory channel and the second data bit corresponding to the particular address on the second memory channel.

An information handling system, comprising;

• a memory controller for dual-channel Dual In-Line Memory Module (DIMM), the memory controller configured to provide memory transactions on a first memory channel and a second memory channel;
• and
• a dual-channel DIMM comprising:
• a first bank of Dynamic Random Access Memory (DRAM) devices configured to provide a first memory transaction on the first memory channel;
• a second bank of DRAM devices configured to provide a second memory transaction on the second memory channel;
• and
• a plurality of back door communication paths, each back door communication path being between a first data bit of the first bank of DRAM devices and a second data bit of the second bank of DRAM devices, the first data bit corresponding to a particular address on the first memory channel and the second data bit corresponding to the particular address on the second memory channel.
