Abstract:
1. Memory device comprising a stack of layers including: at least one first active layer based on a crystalline ionic and electronic conducting material capable of releasing and accepting at least one ionic species; at least one second active layer based on a crystalline ionic and electronic conducting material capable of releasing and accepting said ionic species; the first active layer and the second active layer being based on a material that is capable of a potential variation higher than or equal to 0.3 volts or 0.5 volts for a variation in the concentration of said ionic species of less than 5% or 10%; at least one layer forming an electrolyte between the first active layer and the second active layer, and based on at least one ionic conducting and electronic insulating material; and a measurement device for measuring the electrochemical potential difference between said first active layer and said second active layer.
