Claim 10:
11. A memory device comprising:
a plurality of resistive switching elements arranged in a matrix of M×N along a first horizontal direction and a second horizontal direction intersecting with each other;
a plurality of first signal lines arranged to be spaced apart from each other in the second horizontal direction, wherein each of the plurality of first signal lines extends in the first horizontal direction and is electrically connected to active electrodes of M resistive switching elements arranged in a line along the first horizontal direction among the plurality of resistive switching elements; and
a plurality of second signal lines arranged to be spaced apart from each other in the first horizontal direction, wherein each of the plurality of second signal lines extends in the second horizontal direction and is electrically connected to two-dimensional electron gases of N resistive switching elements arranged in a line along the second horizontal direction among the plurality of resistive switching elements,
wherein each of the plurality of resistive switching elements includes:
a first oxide layer and a second oxide layer stacked one on top of the other such that an interface is present therebetween, wherein the first oxide layer and the second oxide layer are made of different metal oxides;
the two-dimensional electron gas (2DEG) present in the interface between the first oxide layer and the second oxide layer and functioning as an inactive electrode; and
the active electrode disposed on the second oxide layer,
wherein when a positive bias is applied to the active electrode via the first signal line, an electric field is generated between the active electrode and the two-dimensional electron gas, such that the second oxide layer is subjected to the electric field, and active metal ions from the active electrode are injected into the second oxide layer.
