Abstract
A memory includes a first magnetic layer, a second magnetic layer, a nonmagnetic layer between the first and second magnetic layers, a third magnetic layer synthetic-antiferromagnetic-coupled with the second magnetic layer, and a controller controlling a read operation and a write operation. The write operation includes a first operation, a second operation and a third operation. A first potential of the first magnetic layer is larger than a second potential of the third magnetic layer in the first operation. A third potential of the third magnetic layer is larger than a fourth potential of the first magnetic layer in the second operation. A fifth potential of the first magnetic layer is larger than a sixth potential of the third magnetic layer in the third operation.
