Abstract: A plasma charge transfer device utilizable as a shift register memory and/or display utilizing ionizable gas contained in an enclosure with a plurality of individual transfer electrodes covered with a dielectric material aligned parallel on opposite internal walls of the enclosure, but offset one another, throughout its length. This plasma charge transfer device utilizes: an ionizable gas; an input electrode which can be either directly or capacitively coupled to the gas; capacitively coupling to the gas of oppositely offset transfer electrodes; and the wall voltage which results when charge is transferred as the result of a gaseous discharge occurring between two oppositely offset transfer electrodes -- the additive effect of this wall voltage to an applied voltage such that a gaseous discharge occurs between two transfer electrodes if charge was transferred to one of the electrodes during a previous discharge whereas a gaseous discharge will not occur with this same applied voltage between any two oppositely offset electrodes which do not have the proper charge trapped on the wall of at least one of the electrode pairs. Upon the proper application of command signals, a gaseous discharge can be successively transferred between subsequent oppositely offset transfer electrode pair, one electrode position at a time, or continuously shifted throughout the entire length of the plasma charge transfer device, or may be held stationary at any oppositely offset transfer electrode pair position within the device. When the plasma charge transfer device is used as a shift register memory, information to be retrieved at the register output may be optically or electronically recognized and erased.
