Abstract
A memory device includes a stacked structure, a first conductive type doping layer, a second conductive type doping layer, a first conductive plug and a second conductive plug. The stacked structure is located above the substrate, and includes a plurality of conductive layers and a plurality of insulating layers alternately stacked. A projection area of the first conductive type doping layer is larger than a projection area of the stacked structure. The second conductive type doping layer surrounds the first conductive type doping layer and forms a hetero-junction with the first conductive type doping layer. The first conductive plug is electrically connected to the first conductive type doping layer. The second conductive plug is electrically connected to the second conductive type doping layer. The memory device may be a 3D AND flash memory.
