A ferroelectric capacitor structure variously having ceramic lower and upper electrodes, lower and upper insert layers, metal lower and upper electrodes, and a ferroelectric. The ceramic electrode(s) are variously connected with a writing terminal, and the metal electrodes are variously connected with a reading terminal. The use of a combination of metal and ceramic electrodes avoids both fatigue and leakage current.
