Title:
VARIABLE RESISTANCE ELEMENT, STORAGE DEVICE AND NEURAL NETWORK APPARATUS
Document Type and Number:
Japanese Patent JP2023043142
Kind Code:
A
Abstract:
To provide a variable resistance element having small variation in characteristics.SOLUTION: A variable resistance element according to an embodiment changes to a low resistance state or a high resistance state. The variable resistance element comprises: a first transition metal compound layer; a second transition metal compound layer; and a lithium ion conductor layer. The first transition metal compound layer is connected to a first electrode, and is a metal compound containing lithium ions in a lattice interstice. The second transition metal compound layer is connected to a second electrode, and is a metal compound containing lithium ions in a lattice interstice. The lithium ion conductor layer is provided between the first transition metal compound layer and the second transition metal compound layer, and is a solid material that is permeable to the lithium ions and is less permeable to electrons.SELECTED DRAWING: Figure 1
