Abstract
A variable resistance memory device and a driving method thereof are provided. The variable resistance memory device includes a base layer and a pillar-shaped gate electrode formed on the base layer and extending substantially perpendicular to a surface of the base layer. A current transfer layer is formed to surround the pillar-shaped gate electrode. A variable resistance layer formed in an outer portion of the current transfer layer. A blocking layer blocks a path of current flowing through the current transfer layer based on a voltage applied voltage to the pillar-shaped gate electrode, and diverts the current flowing through the current transfer layer to the variable resistance layer.
