A new, inherently more reliable, method is described for fabricating Permalloy integrated memories. The process uses electrodeposited flux logic Permalloy elements. This permits large area arrays with very favorable magnetic characteristics. Low switching coefficients (

Oeμs) are realizable together with very square-loop switching properties. Memory planes of 256 words × 72 bit and a density of 3500 bit/in
2are currently being fabricated.
