ABSTRACT Apparatus and a method for coupling and uncoupling data- read lines of a memory array to a data bus. The data read-out lines of a memory array which is comprised of any combination of latched or non-latched tri-state memories are coupled to the data bus utilizing a conventional TTL circuit in combination with a power driver to simulate a tri-state buffer circuit. When the power driver removes power from the TTL circuit, a tri-state circuit is simulated; whereas when the power driver applies power to the TTL circuit, it operates in its normal mode and a normal impedance is presented between the data bus and the data-out lines of the memory array. -1-
