    摘要: A multi-layer printed circuit board that includes a first layer and a second layer that have first and second signal traces, respectively. The multi-layer printed circuit board includes a via that couples a signal transmitting component to the second signal trace and a throttling member, which is coupled to the first signal trace. The throttling member reduces the speed at which a first signal routed over the first signal trace travels when compared to the speed at which that signal would have traveled had the throttling member been absent.

    摘要: A computer system memory module includes a bi-directional repeater hub that in a first direction takes as an input a memory bus signal in a first port, regenerates the memory signals, and outputs the regenerated memory signal at a second port as at least one separate signal for coupling to a memory bus for each of the regenerated separate signals. In a second direction, the bi-directional repeater hub takes as input at least one memory bus signal at the second port, regenerates each input memory bus signal, and outputs the regenerated memory signal at the first port for coupling to a memory bus.

    摘要: A printed circuit board includes a first component mounted on a first side of the printed circuit board. A second component has an identical pin-out as the first component. The second component is mounted on a second side of the printed circuit board. A first signal line connects a first landpad coupled to a first contact on the first component with a second landpad coupled to a corresponding first contact on the second component. A second signal line connects a third landpad coupled to a second contact on the first component with a fourth land pad coupled to a corresponding second contact on the second component. The first signal line has is equal in length to the second signal line.

    摘要: A serial memory architecture. A memory subsystem includes a bus and a first memory module coupled to the bus. The first memory module has a first connector to receive bus signals from the bus and a second connector to output the bus signals. A second memory module has a first connector to receive the bus signals from the second connector of the first memory module. The bus signals are thereby routed through the memory modules in a serial manner. In one embodiment the memory modules include one or more 90.degree. routing paths between connectors and the devices of the memory modules. In one embodiment, trace lengths are matched.

In a second direction, the bi-directional repeater hub takes as input at least one memory bus signal at the second port, regenerates each input memory bus signal, and outputs the regenerated memory signal at the first port for coupling to a memory bus. A method includes determining whether a memory device to which signals are addressed is on a first memory module. Signals are routed to a first memory bus on the first memory module connected to the memory device if the memory is on the first memory module. Signals are routed to a second memory bus on a second memory module if the memory device is not on the first memory module.
