Patent ID: 7590797

Claim:
A memory module comprising; a circuit board; a memory hub positioned on the circuit board; a plurality of memory devices positioned around the memory hub and arranged in pairs on the same side of the circuit board as one another, each memory device having the same physical pin layout and including pins associated with a first functional group of signals adjacent a first end of each memory device and pins associated with a second functional group of signals adjacent a second end of each memory device, and the first end of each memory device in each pair being positioned adjacent one another on the circuit board and the second end of each device in a pair being positioned adjacent a second end of a device in one of the other pairs; a plurality of command-address busses, each command-address bus coupled to a port on the memory hub and at least one of the pins associated with the second functional group of signals on each of the at least two memory devices, the two memory devices being from a different pair; and an edge connector positioned along an edge of the circuit board and coupled to the memory hub.
