Abstract: Apparatus, assemblies, and platforms employing modular power voltage regulator (VR) modules to provide power to memory modules. A power VR module includes VR circuitry integrated on or coupled to a substrate with wiring coupling the VR circuitry to connector elements in first and second connector means. An assembly further includes a pair of memory modules (e.g., DDR) that are coupled to a power VR module via mating connector means. The connector means may be coupled using a Compression Mount Technology (CMT) connector disposed between arrays of CMT contact pads on the power VR module and the memory modules, or may comprise BGAs, PGAs, and LGAs. The power VR module receives one or more input voltages via one or both memory module and provide various output voltages to each of the memory modules to power memory devices and other circuitry on those modules.

Abstract: In one embodiment, an apparatus includes first and second via structures in a substrate. Each via structure defines a coupling element that extends from the via structure toward the other via structure such that the coupling elements capacitively couple with one another in an area between the first and second via structures.
