    Abstract: There is provided a gap coupling type bus system, which makes it possible to mutually transfer data between all the modules connected to the bus. The gap coupling type bus system comprises for at least three modules, each module being provided with at least one sending/receiving circuit for sending and receiving a signal: at least three signal lines (21-26) respectively connected to the at least three modules (11-16); and terminating resistors (31-36) connected to respective signal lines at the other ends of the signal lines, each terminating resistor having generally same value as characteristic impedance of the signal line. Those at least three signal lines (21-26) have portions (1-2, 1-3, 2-3, . . . ) laid in parallel with one another with a predetermined gap, correspondingly to every combination of different two modules out of those at least three modules (11-16).

    Abstract: Fault tolerance is incorporated within the integral electric heaters of a reworkable electronic semiconductor component, such as a reworkable multi-chip module, to increase production yield and longevity of the rework feature. Components of the foregoing kind contain a multilayer substrate to bond to a printed wiring board, and, for rework, the component includes a plurality of electric heaters arranged side by side on a bottom layer of the substrate. When energized with current, the heaters generate sufficient heat to weaken the adhesive or solder bond to the printed wiring board without delaminating the layers of the substrate, allowing the electronic semiconductor component to be pulled away from the printed wiring board for rework. Additional circuitry is included to automatically route heater current around, that is bypass, any current-interrupting break(s) as may form in any of the electric heaters giving the heaters a fault tolerance.

    Abstract: The present invention provides a double-sided memory module with improved memory device density and improved manufacturability, and with optional bus terminations mounted directly on the memory module for use with high speed, impedance-controlled memory buses. It also allows the same memory devices to be used on both sides of the card, instead of requiring memory devices with mirrored I/O connections on a second side as on prior art double-sided memory cards. The memory module may be formed on a conventional printed circuit card using cost-effective printed circuit board line widths and spaces with unpacked or packed memory chips attached directly to the memory module, while maintaining good signal integrity. Using memory modules with bus terminations mounted directly on the module improves the signal quality and integrity even further and therefore enhances system performance. Such designs may also eliminate the need for bus exit connections, thereby allowing the freed-up connection capacity to be used to address additional memory capacity on the module.

    Abstract: A flexible circuit member includes first and second pseudo-twisted flexible conductors on a flexible dielectric substrate. The first pseudo-twisted conductor is on a first side of the substrate and the second pseudo-twisted conductor is on a second side of the substrate. Each pseudo-twisted conductor includes a periodic pattern with the first pseudo-twisted conductor being shifted longitudinally relative to the second pseudo-twisted conductor by one half of a period of the periodic pattern. A set of first and second additional conductors are also provided on the dielectric substrate. The first additional conductor is on the first side of the substrate and is spaced from and generally follows the shape of the first pseudo-twisted conductor. The second additional conductor is on the second side of the substrate and is spaced from and generally follows the shape of the second pseudo-twisted conductor. These first and second additional conductors may be coupled to reference or ground potential so as to provide a grounding system for the flexible circuit member.

    Abstract: A method for designing a decoupling circuit for a source line of a LSI includes the steps of determining the capacitance of the decoupling capacitor based on the electric charge necessary for one cycle operation of the LSI and the allowable fluctuation of the source voltage, and determining the inductance of the source line based on the impedance of the decoupling capacitor and the allowable minimum multiplexing ratio of the source current by the decoupling capacitor.

    Abstract: A high frequency bus system which insures uniform arrival times of high-fidelity signals to the devices on the high frequency bus, despite the use of the bus on modules and connectors. A high frequency bus system includes a first bus segment having one or more devices connected between a first and a second end. The first bus segment has at least a pair of transmission lines for propagating high frequency signals and the devices are coupled to the pair of transmission lines. The high frequency bus system also includes a second bus segment which has no devices connected to it. The second bus segment also has at least a pair of transmission lines for propagating high frequency signals. The first end of the first segment and second end of the second segment are coupled in series to form a chain of segments and when two signals are introduced to the first end of the second bus segment at the substantially the same time, they arrive at each device connected to the first bus segment at substantially the same time. Also, when two signals originate at a device connected to the first bus segment at substantially the same time, they arrive at the first end of the second bus segment at substantially the same time. Uniform arrival times hold despite the use of connectors to couple the segments together, despite the segments being located on modules, without the need for stubs, despite the presence of routing turns in the segments and despite the type of information, such as address, data or control, carried by the signals.
