This disclosure concerns a driving method of a memory having cells of floating body type which comprises executing, during a write operation, a first cycle of applying a first potential to the bit lines corresponding to the first selected cells and of applying a second potential to the selected word line to write first data; executing, during the write operation, a second cycle of applying a third potential to the bit lines corresponding to a second selected cell among the first selected memory cells and of applying a fourth potential to the selected word line to write second data, wherein the second potential is a potential biased to a reversed side against the polarity of the carriers with reference to potentials of the source and the first potential, and the fourth potential is a potential biased to same polarity as the polarity of the carriers with reference to the potentials of the source and the third potential. |
