| abstract |
In the present invention at least two rows of plasma charge transfer devices have their holding arrays of electrodes connected to a common sequential potential source while the stepping and entering arrays of each row are connected to independent sequential potential sources. Each independent source is controlled by a logic means, such that an input character signal, applied to all the rows of transfer devices, will only be entered and stepped through those rows that are selected by the logic means for having the sequential potential applied to their stepping and entering arrays. Signals already entered in the rows not selected will be held in place. |
