A Coincident-Current Magnetic Memory Cell for the Storage of Digital Information, 1952 April

 File — Multiple Containers
Identifier: 16
Scope and Contents MIT DIC 6889. Project Whirlwind Controlled Distribution Memo 6D-95. A small, ring-shaped, ferromagnetic core with properly "rectangular" B-H characteristics may be operated so that its flux polarity reverses only when the correct combination of two or three magnetizing windings are coincidentally excited. Such cores may then be used as memory devices and assembled into a two- or three-dimensional memory system with storage-cell selection at the intersection of two or three space...
