The Transpolarizer: An Electrostatically Controlled Circuit Impedance with Stored Setting

This new device operates by the controlled transfer of polarization through two or more ferroelectric dielectric sections in series and therefore is named "transpolarizer." It represents a new basic means for storing and gating electrical signals and, in general, means to control circuit impedance in any predetermined manner according to a stored setting. The operation of a two section transpolarizer is described. The unique storage, switching, and control properties of the transpolarizer open a large field of new applications and permit production of new devices and systems such as: recording and reproducing of intelligence in general and, more particularly, switching with a permanent setting, small and large scale storage devices with nondestructive readout, decoders, function generators, etc.
