    Abstract: In order to demodulate an amplitude-modulated signal, two capacitors (C1, C2) are provided to which a signal rectified by a diode (D1) and having a voltage (U1) can be fed. The half-waves of this signal are used by a switch (S3) for alternately charging the first or second capacitor. The capacitors (C1, C2) are discharged by the switches (S1, S2). A comparison of the amplitude values, stored in the capacitors (C1, C2), of the successive half-waves which is carried out in an evaluation unit (AE) enables the execution of a simple and precise demodulation, which can be implemented using few components and at very high frequencies.

    Abstract: An integrated memory contains two normal read amplifiers and two first redundant read amplifiers. It also contains bit lines which are combined into at least two individually addressable normal columns, at least one of which from each normal column is connected to one of the normal read amplifiers. It also has first redundant bit lines which are combined into one individually addressable redundant column, at least one of which is connected to one of the redundant read amplifiers. The first redundant read amplifier and its redundant columns are provided for replacing the two normal read amplifiers and one of the normal columns.
