ABSTRACT:
A new and improved write and read control circuit for semiconductor memories is provided that comprises a first pair of transistors having their emitter terminals coupled to a current source, a base terminal of a first of the first pair being disposed for receiving data to be written in the array and a base terminal of a second of the first pair being coupled to a first reference potential, and each of the first pair of transistors having collector terminals; a second pair of transistors having their collector terminals coupled to a second reference potential, the base terminal of a first of the second pair being coupled to the collector terminal of the first of the first pair of transistors and the base terminal of a second of the second pair being coupled to the collector terminal of a second of the first pair, the emitter terminal of the first of the second pair being coupled to a second current source and forming a first output of the circuit, and the emitter terminal of the second of the second pair being coupled to a third current source and forming a second output of the circuit.
