ABSTRACT:
An output circuit having an output switch controlled by a current steering means which steers the emitter current from the selected memory storage location to the output switch as a function of magnitude to provide an appropriate logic voltage output. An enable switch interconnects the storage matrix and the output circuit.
A fusing circuit includes a current sink connected in parallel with the output circuit for developing sufficient current through a selected storage location whenever a voltage is applied at the output and the operating voltage for the memory storage matrix is raised.
