Abstract
Provided is a current steering element that can prevent write didturb even when an electrical pulse with different polarities is applied and that can cause a large current to flow through a variable resistance element. The current steering element includes a first electrode (), a second electrode (), and a current steering layer (). The current steering layer () comprises SiN(where 0<x≦0.85) added with hydrogen or fluorine. When D (D=D×10atoms/cm) represents a density of hydrogen or fluorine, d (nm) represents a thickness of the current steering layer (), and V(V) represents a maximum value applicable to between the first electrode () and the second electrode (), D, x, d, and Vsatisfy the following Formulae.(ln(10000(·exp(α·)exp(β·)))γ)(ln(1000(·exp(α·)exp(β·)))γ)−(ln(10000(·exp(α·)exp(β·)))γ)/2≧0
