Abstract

In the cases of performing programming by forming a two-terminal-type variable resistance element on a semiconductor device, it has been difficult to control the programming, and malfunctions have often occurred. This switching element includes at least a first variable resistance element, a second variable resistance element, a first rectifying element, and a second rectifying element, one end of the first variable resistance element and one end of the second variable resistance element are respectively connected to one end of the first rectifying element and one end of the second rectifying element, and each of the rectifying elements has two terminals.
