Abstract
A configuration for self-referencing a ferroelectric memory cell reads out the ferroelectric memory cell successively while a bit line is precharged to two different, opposing voltages. The voltage values read out from the ferroelectric memory cell are temporarily stored respectively in a first and a second capacitor and then fed to an evaluator circuit.
