Abstract
A branched transmission line, used for delivering control signals to integrated memory circuits. Memory circuits require control signals, which are delivered on control lines. If multiple memory circuits are involved, multiple control lines are used. If the multiple control lines branch from a common branch point on a supply line, undesirable reflections can occur. The invention reduces the reflections, by distributing the branching, as by starting with three initial branches, each of which branches into three other branches, in order to feed nine memory circuits.
