Three-dimensional memory module architectures
First Claim
1. A memory module comprising:
- a memory-controller layer including at least one memory controller;
at least one memory layer in a stack with the memory-controller layer;
at least one set of through vias extending approximately perpendicular to a surface of the least one memory controller through the stack, wherein the at least one set of at least one through vias provide electronic communication between the at least one memory controller and one of the at least one memory layers.

Abstract
Various embodiments of the present invention are directed to stacked memory modules. In one embodiment of the present invention, a memory module comprises at least one memory-controller layer stacked with at least one memory layer. Fine pitched through vias (e.g., through silicon vias) extend approximately perpendicular to a surface of the at least one memory controller through the stack providing electronic communication between the at least one memory controller and the at least one memory layers. Additionally, the memory-controller layer includes at least one external interface configured to transmit data to and from the memory module. Furthermore, the memory module can include an optical layer. The optical layer can be included in the stack and has a bus waveguide to transmit data to and from the at least one memory controller. The external interface can be an optical external interface which interfaces with the optical layer.
