Abstract: A charge transfer memory has a read-in chain, and assigned parallel chain and a read-out chain, each consisting of charge transfer elements. An additional parallel chain of charge transfer elements stores bias charges which are fed into the read-in chain, after the transfer of information charges from the read-in chain into the parallel chain, before a renewed serial input of information charges into the read-in chain. The read-out chain has a circuit arrangement assigned thereto which fills the output chain with bias charges upon the serial read-out of charges which characterize the information. The read-out chain has assigned thereto a further parallel chain of charge transfer elements with which the bias charges are removed from the output chain before the renewed delivery of charges characterizing information from the parallel chain.

Abstract: A CCD storage module has storage positions which are arranged in cascade and which are formed with the aid of electrodes arranged in insulated fashion above a semiconductor substrate. In respect of each storage position, an item of information, incoming as a binary number comprising n bits, is stored in that a quantity of charge composed of small i unit charges is stored in respect of each storage position, where i corresponds to the value of the binary number of the information. For analysis of the quantity of charge eminating from the last storage position of the cascade of storage positions, in a cascade with the last storage position (2.sup.
