    Abstract: A gap-coupling bus system in which data can be transferred between all modules connected to a bus. The gap-coupling bus system has at least three modules (11-16) which each have at least one transmission/reception circuit, at least three signal lines (21-16) whose one ends are connected to the modules (11-16) respectively, and terminating resistors (31-36) which are connected to the other ends of the signal lines (21-26) and whose resistance values are nearly the same as the characteristic impedances of the signal lines (21-26). The at least three signal lines (21-26) have portions (1-2, 1-3, 2-3, ...) where the signal lines of two different modules among the at least three modules (11-16) are in parallel with each other.

    Abstract: A circuit board (32) such as a memory module board mounts a plurality of memory modules (40) that are electrically connected to a module bus (36) on a first surface of the board (32). The module bus is coupled to a connector (34) at a first end thereof that permits an electrical coupling of a plurality of electrical conductors of the module bus to an external large integrated circuit board, and a terminating resistor device (42) at a second end thereof for properly terminating predetermined ones of the plurality of electrical conductors of the module bus. The module bus (36) is extended beyond the last memory module (40) along the bus by a length which is sufficient to substantially limit reflections and/or crosstalk between the conductors and thereby improve signaling along the module bus. In a first embodiment, the module bus (36) is extended around an edge of the board and for a predetermined distance over any unused portions of the backside of the board (32). In a second embodiment, the module bus is extended for a maximum predetermined distance along any unused portions of the front side of the board (32) when the backside of the board is unavailable for extending the module bus (36).

    Abstract: A flat flexible electrical cable includes a pair of pseudo-twisted conductors (3a, 3b) on a flexible dielectric substrate (2, d). Each conductor includes alternate straight (4) and oblique (5) sections. The straight sections (4) of the conductors are generally parallel to each other and of uniform width. The oblique sections (5) of the conductors cross each other at a crossover point (8). Each oblique section (5) of each conductor is reduced in width uniformly in a direction from the straight-to-oblique transfer point (7) of the respective conductor to the crossover point (8) of the conductors (3a, 3b).
