    Abstract: A multi layer printed circuit board with a 3-load topology is disclosed. First, second, and third integrated circuit (IC) printed wiring board packages having first, second, and third sets of terminals respectively are mounted on opposite sides of the board so that the second set of terminals are directly opposite the third set of terminals. Each package contains an IC die coupled to the respective set of terminals. The IC die in the first package is substantially identical to the one contained in the second package, and different than the one contained in the third package. For improved fanout of the metal lines that interconnect the first package to the second and third packages, each of the first, second, and third sets of terminals in the packages is arranged in substantially a U-shape. Each set of terminals has the same set of signal assignments of a parallel bus implemented by metal lines in the board. The 3-load topology is particularly useful for personal computer motherboard units having twin processors and a bridge chip set, yielding a motherboard having significantly lower number of metal layers, a faster bus and significantly improved noise margin, all with high density IC packages on a wide parallel bus.

    Abstract: An electronic assembly includes one or more discrete capacitors (506, 804, 1204), which are vertically connected to a housing, such as an integrated circuit package (1704). Surface mounted capacitors (506) are vertically connected to pads (602) on a top or bottom surface of the package. Embedded capacitors (804, 1204) are vertically connected to vias (808, 816, 1210, and/or 1212) or other conductive structures within the package. Vertically connecting a surface mounted or embedded capacitor involves aligning (1604) side segments (416) of some of the capacitor's terminals with the conductive structures (e.g., pads, vias or other structures) so that the side of the capacitor upon which the side segments reside is substantially parallel with the top or bottom surface of the package. Where a capacitor includes extended terminals (1208), the capacitor can be embedded so that the extended terminals provide additional current shunts through the package.

    Abstract: Switching noise within an LGA-packaged or PGA-packaged IC Vdd and IC Vss nodes is reduced by spreading the electrical current in the bypass path to reduce the effective current loop area, and thus reduce the energy stored in the magnetic field surrounding the current path. This result is achieved by minimizing the horizontal components of the linkage paths between the IC nodes to be bypassed and the bypass capacitor. Since effective inductance Leff seen by the bypass capacitor is proportional to magnetic energy, Leff is reduced over a broad band of frequencies. For each bypass capacitor, a pair of conductive vias is formed. A first via is coupled to the LGA package Vcc plane and to the IC Vdd node, and a second via is coupled to the LGA package Vss plane and to the IC Vss node. These vias preferably are spaced-apart a distance &Dgr;X corresponding to the distance between first and second connections on the bypass capacitor although sub-mm offsets in a via at connections may be used to accommodate differing connection pitches. The bypass capacitor connections are coupled to the lower surfaces of the first and second vias, at the lower surface of the LGA package. When the package is inserted into a socket, the bypass capacitor extends into at least some of the otherwise unused recess in the socket. Multiple bypass capacitors are accommodated by forming additional spaced-apart vias that may be electrically parallel-coupled.

    Abstract: A memory system is disclosed. The memory system comprises a circuit board and at least two memory devices mounted on the circuit board. Each of the at least two memory devices includes a plurality of pins for receiving and providing signals. At least a first portion of the pins of one of the at least two memory devices are coupled to at least a second portion of the pins of the other at least two memory devices such that a pair of the first portion coupled to a pin of the second portion forms a coupled load. The coupled load then appears as one load. Accordingly, in a system in accordance with the present invention, at least two memory devices are provided on a circuit board. Each of the at least two memory devices includes a plurality of pins. At least a portion of the pins of one of the two memory devices is in close proximity to and coupled to the at least a portion of the pins of the other of the at least two memory devices such that a pin and one memory device is coupled to a pin on the other memory device to form a coupled load. The coupled load then appears as one load. This is accomplished in a preferred embodiment by allowing the pins which are on opposite sides (front and back) of a printed circuit board to be represented as one load and then remapping one of the oppositely disposed pins to have the same functionality as the other oppositely disposed pin.
