Abstract
An apparatus and method to permit reconfiguration of a memory topology. A printed circuit board (PCB) has a central processing unit (CPU) connector coupled a pair of dual inline memory module (DIMM) connectors coupled thereto. The PCB defines an electrical access channel coupling the pair of DIMM connectors into a T topology having a first branch and a second branch. The second branch of the T topology is electrically discontinuous with the rest of the T topology proximate to a T junction. A bridge may be provided to span the discontinuity.
Claims22
An apparatus to permit reconfiguration of a memory topology comprising:
- a printed circuit board (PCB);
- a central processing unit (CPU) socket coupled to the PCB;
- a pair of dual inline memory module (DIMM) connectors coupled to the PCB;
- an electrical access channel defined by the PCB coupling the pair of DIMM connectors into a T topology having a first branch and a second branch, wherein the second branch of the T topology is electrically discontinuous proximate to a T junction.
A method comprising:
- defining a memory access channel on a printed circuit board (PCB), the memory access channel having a T topology having a first branch electrically continuous with a junction of the T and a second branch electrically discontinuous with the junction of the T;
- exposing contact points for both the first and second branch on a surface of the PCB;
- coupling a first DIMM slot to the first branch on the PCB;
- coupling a second DIMM slot to the second branch on the PCB;
- and
- providing a removable bridge to electrically connect between the exposed contact points.
A mobile system with a reconfigurable memory topology comprising:
- a mobile platform including a display;
- a motherboard within the mobile platform having a first and second dual inline memory module (DIMM) slot;
- a central processing unit (CPU) coupled through the motherboard to the DIMM slots in a T topology;
- wherein a first branch of the T topology is electrically continuous between a T junction and the first DIMM slot, and a second branch defines a gap proximate to the T junction such that the second branch is electrically discontinuous between the T junction and the second DIMM slot.
