1. A method of driving a semiconductor integrated circuit system, comprising:

  • phase-changing a selected memory cell area to a reset state;

    detecting a phase-change resistance of a memory cell area adjacent to the selected memory cell area on the same phase-change line;

    generating a correction current in response to a detection result of the phase-change resistance of the adjacent memory cell area; and

    maintaining a phase-change state of the adjacent memory cell area by applying the correct current to the adjacent memory cell area.
