Abstract : Materials have recently been discovered within which exist domains of permanent electric dipoles. These materials, named ferroelectrics, can be used to advantage in many electronic applications where ferromagnetic materials are currently used, often in circuits which are the duals of those of their ferromagnetic counterparts. Ferroelectrics can be made in the form of single crystals or rugged cermics. Digital information can be stored in a matrix of ferroelectric condensers, and an efficient method of storage-element selection is available in the form of a two-coordinate, coincident-voltage scheme. The matrix can be made on a thin ferroelectric sheet by painting the coordinate rows on one side and the coordinate columnss on the other. The information can be taken from the matrix via a simple mixing transformer.
