Abstract
A semiconductor device includes a substrate extending in a horizontal direction. An active pillar is present on the substrate extending in a vertical direction relative to the horizontal direction of extension of the substrate. A variable resistive pattern is present on the substrate extending in the vertical direction along the active pillar, an electrical resistance of the variable resistive pattern being variable in response to an oxidation or reduction thereof. A gate is present at a sidewall of the active pillar.
