Assignee: MARVELL ASIA PTE LTD
Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 8:
9. A method of operating a multi-chip module (MCM), the MCM including a substrate, a first integrated circuit, and a second integrated circuit, the first integrated circuit and the second integrated circuit being disposed on the substrate, and a first signaling channel comprising a circuit trace electrically coupling the first integrated circuit and the second integrated circuit, the method comprising:
transmitting first data from the first integrated circuit to the second integrated circuit via the first signaling channel in a first direction;
while concurrently transmitting the first data in the first direction, receiving at the first integrated circuit second data transmitted from the second integrated circuit via the first signaling channel in a second direction opposite to the first direction; and
preventing echo interference associated with concurrently transmitting the first data from being output from a receiver of the first integrated circuit by canceling the echo interference at the receiver or prior to the echo interference being received at the receiver.
