Abstract:
1. Non-volatile memory device comprising: generating means suited to applying at least one given quantity of electricity to a stack of layers comprising, on either side of an electrolyte: at least one first active layer based on a first ion and electron conductor crystalline material, suited to releasing and/or accepting at least one ion species, and the electrochemical potential of which is capable of undergoing, following an injection of said given quantity of electricity into said stack, at least one first given variation between at least one first value and at least one second value, at least one second active layer based on a second ion and electron conductor crystalline material, suited to releasing and/or accepting at least one ion species, and the electrochemical potential of which is capable of undergoing, following an injection of said given quantity of electricity into said stack, at least one second variation between at least one third value and at least one fourth value, said second variation being lower than said first variation, said third value and said fourth value being between said first value and said second value.
