    摘要: A phase change memory device is provided which includes a memory cell array including a plurality of memory cells, and a write driver for supplying a program current to the memory cell array through a global bitline. The memory cell array includes first and second cell regions, a first local bitline connected to the first cell region, a second local bitline connected to the second cell region, and a select region disposed between the first and second cell regions and supplying the program current supplied through the global bitline to the first and second local bitlines in response to a local select signal.
