Abstract:
A variable resistance memory may include first and second conductive elements spaced apart from each other on a variable resistance layer. The variable resistance layer may include first to third oxide layers sequentially arranged in a direction perpendicular to a direction in which the first and second conductive elements are arranged. A dielectric constant of the second oxide layer may be greater than dielectric constants of the first and third oxide layers.
