Patent ID: 7003618

Claim:
A computer system comprising: a circuit board; a controller device having an interface, wherein the controller device is disposed on the circuit board; a first socket, disposed on the circuit board, to receive a first module having a first integrated circuit buffer device, the first module having a first plurality of integrated circuit memory devices coupled to the first integrated circuit buffer device; a first point-to-point link coupled to the interface of the controller device, wherein, when the first module is received in the first socket, the first integrated circuit buffer device receives control information, address information, and data from the controller device over the first point-to-point link; and a second socket, disposed on the circuit board, to receive a second memory module having a second integrated circuit buffer device, the second module having a second plurality of memory devices coupled to the second integrated circuit buffer device, wherein, when the first module is received in the first socket and the second module is received in the second socket, the second integrated circuit buffer device receives the data, the control information and the address information from the first integrated circuit buffer device over a second point-to-point link.
