    • Magnetic matrix memory apparatus comprises a set of juxtaposed row conductive wires and a set of juxtaposed column conductive wires arranged orthogonally and adjacent to but insulated from the row conductive wires. Each of the row conductive wires is composed of a conductive spring wire having directly and uniformly deposited thereon a ferromagnetic thin film having substantially rectangular hysteresis characteristics and an inherent anisotropy. At least one of the sets of conductive wires is bonded to a sheet of insulation substratum. The ferromagnetic thin film of each row conductive wire forms closed magnetic circuits with respect to flux caused by current passed through the wire. Means is provided for applying an information signal to at least one wire of one of the sets of wires and for applying an exciting signal to at least one of the other set of wires. The inherent anisotropy of the thin film is established in a plane substantially orthogonal to the axis of the conductor to be employed for applying the information signal whereby a bit of information is stored in the ferromagnetic thin film deposited around at least one selected intersection between the two sets of wires in the state of direction of the residual magnetism of the magnetic thin film when selection is made by energizing with the information signal and the exciting signal at least one selected row conductive wire and at least one selected row conductive wire and at least one selected column conductive wire. A bit of information thus stored is read out from at least one wire employed for applying the information signal as an output signal having substantially the same amplitude and either of opposite polarities determined by the direction of the residual magnetism. of the residual magnetism of the magnetic thin film when selection is made by energizing with the information signal and the exciting signal at least one selected row conductive wire and at least one selected column conductive wire.
