Abstract: In a process for operating a charge shift store in which, for the regeneration of the data contained in storage loops, the data is advanced over regeneration stages in dependence upon a regeneration pulse train. In the input and output processes, items of data are written in via an input stage and read out via an output stage in dependence upon an operating pulse train. The items of data contained in the storage elements of the individual storage loops are regenerated in a full cycle only after the expiration of the maximum storage time of the storage elements. The operating pulse train is employed as a regeneration pulse train in this process.
