ABSTRACT:
Exemplary embodiments of the present invention provide set programming methods and write driver circuits for a phase-change memory array. An exemplary embodiment of a set programming method may comprise applying a set current pulse to the phase-change cells, which may cause phase-change cells, which may be included within the phase-change memory array, to transition to the set resistance state. Exemplary embodiments of the set programming methods and/or write driver circuits may result in the phase-change cells to transition to the set resistance state.
