    摘要: A circuit for generating a reference voltage for the reading out from and the evaluation of read output signals which are read out with a constant plate voltage from storage cells of a ferroelectric memory via bit lines. In the circuit, a reference voltage device is formed of two reference cells that are subjected to the action of complementary signals. The reference cells can be simultaneously read out in order to generate the reference voltage in a selection and evaluation device.
