    Abstract: Apparatus for supplying selection lines of a magnetic core memory with drive currents of uniform amplitude and configuration. The apparatus includes a pair of line selection switches at opposite ends of a selection line group for steering current from a source through a selected line and a current regulator that maintains the sum of the currents through the line at a constant level. The lines in the group are terminated by a set of alternately operable termination circuits, which set is common to all of the lines of a coordinate axis of the memory array. The termination circuit serve to damp voltage spikes, ringing oscillations and the inductive energy of the line upon energization and de-energization thereof and to maintain the lines of the memory stack at a fixed potential to prevent the lines from floating due to leakage currents and capacitive voltage build-ups that would establish the lines at different potentials during inactive or memory idle periods.
