  • Digital memory element
    Patent number: 5917747
    Abstract: A digital memory element having three miniaturized electron tubes, which is faster and smaller by at least one further order of magnitude than known digital memory elements, can be produced through conventional and additive lithography. The digital memory element is a small memory capacitor linked to the anode of a write-in tube, to the cathode of an erase tube, and to a deflection element of a read-out tube which deflects an electron beam, in dependence upon the charge state, to one of two detectors.
