APPARATUS AND METHODS FOR A PHYSICAL LAYOUT OF SIMULTANEOUSLY SUB-ACCESSIBLE MEMORY MODULES
First Claim
1. A memory module for use in a computer system having a memory interface, comprising:
- a printed circuit board having a plurality of sectors, each sector being electrically isolated from the other sectors and having a multi-layer structure;
at least one memory device attached to each sector of the printed circuit board, the memory devices being organized into a plurality of memory ranks; and
at least one driver attached to the printed circuit board and operatively coupled to at least one of the memory devices from each of the memory ranks, the driver being adapted to be coupled to the memory interface, wherein the memory ranks are either individually or simultaneously, or both individually and simultaneously accessible by the driver so that one or more memory ranks on a particular sector may be accessed at one time.

Abstract
A layout for simultaneously sub-accessible memory modules is disclosed. In one embodiment, a memory module includes a printed circuit board having a plurality of sectors, each sector being electrically isolated from the other sectors and having a multi-layer structure. At least one memory device is attached to each sector, the memory devices being organized into a plurality of memory ranks. A driver is attached to the printed circuit board and is operatively coupled to the memory ranks. The driver is adapted to be coupled to a memory interface of the computer system. Because the sectors are electrically-isolated from adjacent sectors, the memory ranks are either individually or simultaneously, or both individually and simultaneously accessible by the driver so that one or more memory devices on a particular sector may be accessed at one time. In an alternate embodiment, the printed circuit board includes a driver sector electrically isolated from the other sectors and having a multi-layer structure, the driver being attached to the driver sector.
