Abstract
Abstract Storage element for information using electrochemical means. Multiple, polarizable storage electrodes are provided and arranged spaced from and opposed to a nonpolarizable counterelectrode, all the electrodes being arranged within a chamber containing an electrolyte. Information is recorded onto the polarizable electrodes in a desired pattern by causing an electron beam to impinge thereon through a junction contact. Information is digitally obtained by directing the electron beam to selected locations which develops a voltage between one of the storage electrodes and the counterelectrode the magnitude of which depends upon the state of polarization of the storage electrode. Such voltage is then measured by an auxiliary electrode and delivered as an output.
