Dynamic circuit interface

A circuit interface comprising:

• a connector provided on a circuit board, wherein the connector is configured to receive a first circuit card or a second circuit card;
• a first circuit provided on the circuit board and electrically coupled to the connector;
• and
• a second circuit provided on the circuit board and electrically coupled to the connector, wherein:
• if the first circuit card is received by the connector, a first signal path is provided from the first circuit to the second circuit via the first circuit card, and
• if the second circuit card is received by the connector, a second signal path is provided from the second circuit card to the second circuit.

An information handling system comprising:

• a circuit board, comprising:
• a first circuit and a second circuit, wherein the circuit board is configured to receive a first circuit card comprising a first IC chip or a second circuit card comprising a second IC chip;
• and
• a circuit interface means for electrically coupling the first IC chip to the second circuit when the first circuit card is received by the circuit board, and for electrically coupling the second IC chip to the second circuit when the second circuit card is received by the circuit board.
