Abstract
A random-access memory having a plurality of memory cells each cell including a magnetic storage element in which the magnetic storage element inlcudes a thin film of magnetic material disposed on a semiconductor substrate and having further disposed thereon transistors connected in a flip-flop type of configuration. In a preferred embodiment of the invention, the magnetic storage element comprises a thin magnetic film that has mutually orthogonal remanent magnetization states used for information storage. A pair of strip conductors used to provide connections to the flip-flop configuration of the transducers are magnetically coupled to the mutually orthogonal remanent magnetization states. By providing the thin film having a pair of mutually orthogonal remanent states used for information storage, a storage cell having a relatively high frequency response is provided.
