1. A semiconductor integrated circuit system, comprising:
- a phase-change line including a first phase-change area constituting a first memory cell and a second phase-change area constituting a second memory cell;
a write current providing unit configured to phase-change a selected one of the first and second phase-change areas; and
a phase-change compensation unit configured to restore the other of the first and second phase-change areas by compensating for a dummy phase-change caused in the other phase-change area due to a phase-change of the selected phase-change area.
