Patent ID: 8830718

Claim:
A magnetic memory comprising: a magnetic wire including a first portion and a second portion, having a first electric resistance value between the first portion and the second portion, and configured to form plural magnetic domains which are separated from each other by magnetic domain walls; a first insulating layer formed on the magnetic wire; plural first electrodes formed on the first insulating layer, arranged along the magnetic wire, and spaced from each other; a second electrode including a third portion being closer to the first portion than the second portion, and a fourth portion being closer to the second portion than the first portion, the second electrode electrically connected to the plural first electrodes between the third portion and the fourth portion and having a second electric resistance value being larger than the first electric resistance value; a current supplying module configured to supply the magnetic wire with a pulse current flowing from the first portion to the second portion; and a voltage applying module configured to apply, between the second portion and the fourth portion, a voltage that decreases with time.
