FluxlokߞA Nondestructive, Random-Access Electrically Alterable: High-Speed Memory Technique Using Standard Ferrite Memory Cores

The Fluxlok memory technique uses the principle of cross-field magnetization to achieve the nondestructive sensing of the information state of standard, readily available, ferrite memory cores in a simply wired memory plane. Bipolar output (ONE and ZERO) signals are obtained at the rate of rise of the READ pulse. The signals are unaffected by test temperatures of from ߝ65°C to +100°C. Coincident current WRITE operation or an inherent orthogonal field WRITE may be used. A 2-mc 64-word Fluxlok memory test vehicle is described.
