ABSTRACT:
A three-dimensional memory device having polycrystalline silicon diode isolation elements for phase change memory cells and method for fabricating the same. The memory device includes a plurality of stacked memory cells to form a three-dimensional memory array. The polycrystalline silicon diode element selects the phase change memory cell. The memory device is fabricated by forming a plurality of phase change memory cells and diode isolation elements on a base layer. Additional layers of memory cells and isolation elements are formed over the initial layer.
