Abstract:
A memory cell comprising a ferroelectric capacitor, a variable impedance element and a conductive load is disclosed. The ferroelectric capacitor, characterized by first and second polarization states, is connected between a control terminal and a first switch terminal. The variable impedance element has an impedance between the first and second switch terminals that is determined by a signal on a control terminal. The conductive load is connected between a first power terminal and the first switch terminal. The second switch terminal is connected to a second power terminal. When a potential difference is applied between the first and second power terminals, a potential on the first switch terminal varies in a manner determined by the state of polarization of the ferroelectric capacitor.
