Abstract
A memory device includes a substrate, a first conductive stripe disposed on the substrate and extending along a first direction, a second conductive stripe disposed on the first conductive stripe, a first pillar element and a spacer. The second conductive stripe extends along a second direction intersected with the first direction. A thickness of the second conductive stripe is greater than a thickness of the first conductive stripe, and the second conductive stripe is an integral structure. The first pillar element is disposed at an intersection between the first conductive stripe and the second conductive stripe, and extends from a top surface of the first conductive stripe to a bottom surface of the second conductive stripe along a third direction intersected with the first direction and the second direction. The first pillar element includes a switching layer and a memory layer corresponding to a first level.
