Abstract
A non-volatile variable resistive element according to an embodiment comprises a first electrode including a first metal, a second electrode including a second metal, a third electrode placed opposite to the first and second electrodes, and a variable resistive layer placed between the first and second electrodes and the third electrode, a resistance of the variable resistive layer reducing when at least either one of the first metal and the second metal is diffused into the variable resistive layer and the resistance of the variable resistive layer rising when at least either one of the first metal and the second metal diffused into the variable resistive layer is collected by the first electrode or the second electrode.
