Abstract
A magnetic storage device is provided which has significantly reduced power consumption. In the magnetic storage device, a yoke is arranged so as to circumferentially surround part of a line extending in an arbitrary direction, and a magneto-resistive element to which information can be written by utilizing a magnetic field generated by the line is arranged in the vicinity of the line. In this case, the length of the magnetic path of the yoke is set to 6 μm or less.
Claims20
A magnetic storage device, comprising:
- a line;
- a yoke circumferentially surrounding part of the line in a longitudinal direction;
- and
- a magneto-resistive element arranged in the vicinity of the line, to which information can be written by utilizing a magnetic field generated by the line, wherein
- a length of a magnetic path of the yoke is equal to or less than 6 μm,
- wherein a length of the yoke in a longitudinal direction of the line is shorter than a length of the line in a longitudinal direction;
- a gap is formed in part of the yoke in a circumferential direction;
- and the magneto-resistive element is arranged in or between the gap.
