Abstract
A resistive non-volatile memory cell including a Metal-Insulation-Metal stack including two electrodes and a multilayer of insulation, placed between the two electrodes, including a thin layer of oxide allowing for a resistive transition and an oxygen vacancy reservoir layer is provided. The stack includes from bottom to top: the bottom electrode including a metal layer, the insulation including a layer of stoichiometric metal oxide and a layer of substoichiometric metal oxide forming the oxygen vacancy reservoir layer, and the top electrode including a layer of metal oxide and a metal layer, such that the oxygen vacancy reservoir layer is inserted between two metal oxide stoichiometric layers.
