ABSTRACT:
A phase change memory device resistant to stack pattern collapse is presented. The phase change memory device includes a silicon substrate, switching elements, heaters, stack patterns, bit lines and word lines. The silicon substrate has a plurality of active areas. The switching elements are connected to the active areas. The heaters are connected to the switching elements. The stack patterns are connected to the heaters. The bit lines are connected to the stack patterns. The word lines are connected to the active areas of the silicon substrate.
