This thesis focuses on the understanding of forming mechanisms in oxide-based conductive bridge memories (CBRAM), based on metallic oxides. For this purpose, we compared the memory stack to an electrochemical cell at nanometer scale and consider that the main mechanisms occurring in the memory rely on electrochemical effects. We started our studies from a reference couple CuxTey/Oxide, analyzed by HAXPES and ToF-SIMS before and after electro-forming, in order to observe the diffusions and the modifications of the chemical environment occurring during forming. Then, the ion source layer based on CuxTey alloy and the dielectric (Ta2O5, GdOx or Al2O3) were sequentially modified and results of their analyses were compared to the reference stack...
