A monolithic decode-drive circuit for magnetic memories

The highly replicated decode-drive circuitry of magnetic memories is being produced at a very low cost with batch-fabricated integrated-circuit technology. This has resulted from judiciously reconfiguring traditional circuit forms in order to optimize their fabrication. A new monolithic circuit function and its application are described. The circuit is used for low-cost high-speed 400-mA switching in magnetic memories. The functions of address decoding and timing control are also incorporated into the circuit. The address scheme employs no transformers and possesses the advantages of miniaturization. Details of the circuit configuration, topology, and packaging are described and illustrated.
