Abstract
The memory device has series-connected ferroelectric memory cells in which a series circuit composed of a resistor and/or of a transistor for the ferroelectric capacitor of a respective memory cell is present. As a result, without unacceptably increasing the access time, the interference pulses at the ferroelectric capacitors of the memory cells which are not being addressed at that particular time and which are generated by the reading out or writing of the addressed memory cell are reduced in such a way that they have virtually no further influence on the non-addressed memory cells.
