ABSTRACT:
The present invention is a device and method to change the reflection time of a bidirectional signal so as to cause a false data value to be correctly seen as the proper data value when the bidirectional signal travels between a first semiconductor chip and a second semiconductor chip, through a transmission line between the two semiconductor chips. The reflection time is adjusted by coupling an electrical network to the transmission line to cause an early electrical reflection. In one embodiment, the network is coupled to establish an impedance discontinuity between the board trace and the package trace.
