Abstract
A data storage circuit includes a matrix array of memory cells. The memory cells are configurable and non-volatile. Each one is intended to operate in either one of two operating configurations; the first operating configuration corresponding to a ferroelectric random-access memory; and the second operating configuration corresponding to a metal-oxide resistive random-access memory. Each memory cell comprises: a stack of thin layers in the following order: a first layer made of an electrically conductive material forming a lower electrode, a second layer made of a dielectric and ferroelectric material and a third layer made of electrically conductive material forming an upper electrode.
