摘要:
Magnetoresistive structures, magnetic random-access memory devices including the same, and methods of manufacturing the magnetoresistive structure, include a first magnetic layer (13) having a magnetization direction that is fixed, a second magnetic layer (17) orresponding to the first magnetic layer (13), wherein a magnetization direction of the second magnetic layer (17) is changeable, and a magnetoresistance (MR) enhancing layer (15) and an intermediate layer (16) both between the first magnetic layer (13) and the second magnetic layer(17).
摘要:
Magnetoresistive elements, and memory devices including the same, include a pinned layer having a fixed magnetization direction, a free layer corresponding to the pinned layer, and a protruding element protruding from the free layer and having a changeable magnetization direction. The free layer has a changeable magnetization direction. The protruding element is shaped in the form of a tube. The protruding element includes a first protruding portion and a second protruding portion protruding from ends of the free layer facing in different directions.

摘要:
Provided are information storage devices using movement of magnetic domain walls (DW) and methods of operating information storage devices. An information storage device includes a magnetic track (100) and an operating unit (200). The magnetic track (100) includes a plurality of magnetic domains (D) separated by magnetic domain walls (DW). The size of the operating unit (200) is sufficient to cover at least two adjacent magnetic domains (D). And, the operating unit (200) may be configured to write/read information to/from a single magnetic domain (D) as well as a plurality of magnetic domains (D) of the magnetic track (100).
