Abstract
A phase change memory device and a write method thereof allow writing of both volatile and non-volatile data on the phase change memory device. The phase change memory device may be written by setting a write mode as one of a volatile write mode and a non-volatile write mode, and writing data as volatile or non-volatile by applying a write pulse corresponding to the write mode, wherein, when power is not supplied to the phase change memory device, the non-volatile data is retained and the volatile data is not retained.
