Abstract:
A resistive ferroelectric memory cell, comprising:a selection transistor having first and second zones of a first conduction type; a storage capacitor having one electrode at a fixed cell-plate voltage and another electrode connected to said first zone of said selection transistor; a semiconductor substrate of a second conduction type opposite the first conduction type, said storage capacitor and said selection transistor disposed in said semiconductor substrate, defining a pn junction between said first zone of said selection transistor and said semiconductor substrate; a resistor disposed between the other electrode of said storage capacitor and the one electrode at the fixed cell-plate voltage, said resistor having a resistance R2 such that: R3<2<1, in which;R1 is a reverse resistance of said pn junction between said first zone of said selection transistor and said semiconductor substrate; and R3 is a resistance between said first zone and said second zone of said selection transistor, in a turned-on state.
