Provided are a phase-change memory device and method that maintains a resistance of a phase-change material in a reset state within a constant resistance range. In the method, data is provided to a first phase-change memory cell and then it is first determined whether data stored in the first phase-change memory cell and the data provided to the first phase-change memory cell are identical. If the data stored in the first phase-change memory cell and the data provided to the first phase-change memory cell are not identical, a complementary write current is provided to the first phase-change memory cell and it is second determined whether the data stored in the first phase-change memory cell and the data provided to the first phase-change memory cell are identical. If the data stored in the first phase-change memory cell and the data provided to the first phase-change memory cell are identical, data is provided to a second phase-change memory cell.
