Abstract: An semiconductor device, containing logic blocks and high speed connections between the blocks, where the connections utilize current direction for logic representation rather than voltage level. Such high speed connections comprise differential transmitters which drive a pair of adjacent wires with differential current pulses that are received by a differential receiver which may be put in a low power state between transmissions.
