A method and a circuit configuration for generating a reference voltage in
a resistive semiconductor memory includes generating a reference voltage
by connecting together two bitlines having different voltages. This
method for generating a reference voltage can be used in a method and in
a circuit configuration for reading at least one memory cell of a
resistive memory cell array in a semiconductor memory. The generated
reference voltage and a voltage dependent on the content of a resistive
memory cell are applied to an amplifier to determine the content of the
memory cell. The content of the memory cell is determined dependent on a
relationship between the reference voltage and the voltage dependent on
the content of the memory cell.
