Abstract
Current control systems and methods are provided for a plurality of integrated circuit devices that are commonly attached to a bus, including a plurality of signal lines. Each integrated circuit includes a plurality of output drivers, a respective one of which drives a respective one of the plurality of signal lines. Each integrated circuit includes a current setting circuit that sets an output current for each of the output drivers in the integrated circuit. A controlling circuit controls the current setting circuit in each integrated circuit, such that each current setting circuit simultaneously sets an output current for an output driver corresponding to a different one of the plurality of signal lines.
