Abstract
Abstract A regenerating circuit for binary signals in the form of a keyed flip-flop with one labile and two stable points has at least two inverting amplifier stages, featuring feedback, in particular for the stored signals and for the read-out signals of integrated single transistor storage elements which form a storage field. The storage elements of the storage field are connected by way of a digit line to the regenerating circuit and the inverting amplifier stages may be adjusted into the region of the labile point of the circuit by means of a feedback device by way of an inverter stage or an odd number of inverter stages.
