A new technique for using thin magnetic films as a phase script memory element

The use of thin magnetic film memories for high speed computers has been well established. More recently, efforts have been made to adapt thin-film memory elements for operation in a phase script mode by using drive fields at two different frequencies to switch and read the state of the memory element. The resulting memory system is uniquely suited for operation in a parametron computer where information exists as a phase state rather than an amplitude state.
