Electrochemical memory device

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/or 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/or accepting said ionic species;
• the first active layer and the second active layer being based on LiMn2O4;
• 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.
