Abstract:
A nonvolatile memory element for storing an information with the utilization of hysteresis characteristics of a ferroelectric, comprising:a first capacitor provided with a ferroelectric film and electrically coupled with first and second ends;a second capacitor provided with a ferroelectric film having a dielectric constant substantially equal to that of said ferroelectric film of said first capacitor and electrically coupled with first and second ends, said second end of said first capacitor being connected to said first end of said second capacitor so that said first and second capacitors are connected in series to each other;means for applying a voltage corresponding to said information between said first end of said first capacitor and said second end of said second capacitor; andprocessing means connected to said first and second capacitors for performing predetermined processing according to a voltage at a point at which said second end of said first capacitor and said first end of said second capacitor are connected.
