Abstract:
1. A multi-channel memory connection system, comprising: a circuit board comprising a plurality of memory connectors configured to receive either a memory module or a memory riser, wherein at least one memory connector includes a primary port connected to at least one bi-directional memory channel on the circuit board and a secondary port connected to the at least one bi-directional memory channel on the circuit board, and the memory riser includes a bi-directional memory channel connectable to the primary port and another bi-directional memory channel connectable to the secondary port, wherein the bi-directional memory channel and the another bi-directional memory channel are not connected and are operable to simultaneously send data to a memory controller, and when the memory riser is connected to the at least one memory connector, the at least one bi-directional memory channel on the circuit board operates as two different bi-directional memory channels comprising a first bi-directional memory channel connected to the bi-directional memory channel in the memory riser via the primary port and a second bi-directional memory channel connected to the another bi-directional memory channel in the memory riser via the secondary port, and when the memory module is connected to the at least one memory connector, the at least one bi-directional memory channel on the circuit board operates as a single bi-directional memory channel at the at least one connector, wherein the single bi-directional memory channel is connected to the memory module via the primary port and the secondary port.
