SEMICONDUCTOR MEMORY DEVICE AND METHOD OF MANUFACTURING THE SAME

摘要

A phase change memory device including plural memory cells is disclosed. Each of the memory cells includes memory transistors and phase change film portions formed above or below the memory transistors. The phase change film portions correspond to the respective memory transistors respectively. Vias are provided in order to connect each of the memory transistor in parallel to each of the phase change film portions in each of the memory cells. The vias connect the memory cells in series to one another.
