Abstract:
A variable resistance memory device includes plural first, second, and third conductors, plural memory cells, and a write circuit. Each memory cell is between one first conductor and one third conductor, and includes a first sub memory cell and a second sub memory cell. The first sub memory cell is between the one first conductor and one second conductor, and includes a first variable resistance element and a first bidirectional switching element. The second sub memory cell is between the one second conductor and the one third conductor, and includes a second variable resistance element and a second bidirectional switching element. The write circuit applies a first potential to the first and third conductors of a selected memory cell, a second potential to the second conductor of the selected memory cell, and a third potential to the first and third conductors of non-selected memory cells.
