Abstract
A magnetic storage device is provided which has significantly reduced power consumption. The magnetic storage device includes: a yoke which is arranged so as to cover part of a line extending in an arbitrary direction; and a magneto-resistive element which is arranged near the line and is capable of writing information using a field occurring from the line. The magnetic storage device is set to satisfy the equation Iw≦a·R+b, where Iw is the write current necessary for the line, R is the magnetoresistance of the yoke, a (mA·H)=7.5E−11, and b (mA)=0.1.
