Abstract
A method is described. The method includes receiving DDR memory channel signals from a motherboard through a larger DIMM motherboard connector. The method includes routing the signals to one of first and second smaller form factor connectors. The method includes sending the DDR memory channel signals to a DIMM that is connected to the one of the first and second smaller form factor connectors.
Claims20
A computing system, comprising:
- a motherboard;
- a semiconductor chip mounted to the motherboard, the semiconductor chip comprising a plurality of processing cores and a memory controller that is coupled to the plurality of processing cores;
- a DIMM connector mounted to the motherboard, the DIMM coupled to the memory controller by way of DDR memory channel signal traces;
- an adaptor card plugged into the DIMM connector;
- first and second DIMMs coupled to the adaptor card with connectors that are smaller than the DIMM connector.
2 more elements
An adaptor card, comprising:
- a PC board substrate;
- a larger DIMM motherboard connector mounted on the PC board substrate;
- and
- first and second smaller DIMM connectors mounted on the PC board substrate, the PC board substrate comprising signal wiring between the larger DIMM motherboard connector and the first and second smaller DIMM connectors.
1 more element
A DIMM, comprising:
- a PC board substrate;
- memory chips mounted on both sides of the PC board substrate;
- and, a small form factor connector mounted on a planar surface of the PC board substrate such that the small form factor connector's electrical interface faces outward from the planar surface of the PC board substrate.
A method, comprising:
- receiving DDR memory channel signals from a motherboard through a larger DIMM motherboard connector;
- routing the signals to one of first and second smaller form factor connectors;
- sending the DDR memory channel signals to a DIMM that is connected to the one of the first and second smaller form factor connectors.
