ABSTRACT:
A semiconductor non volatile memory device capable of multiple write operations with high reliability includes memory cells. Each memory cell of the device has a first electrode, a second electrode, and an information storage section between the two electrodes. A segregation of composing elements of the information storage section caused by applying a first current pulse from the first electrode to the second electrode is corrected by applying a second current pulse from the second electrode to the first electrode such that the composition of the storage section recovers to its original state.
