Abstract:
1. A magnetic random access memory comprising: a magnetoresistive effect element which includes a fixed layer having a fixed magnetization direction, a recording layer having a reversible magnetization direction and a non-magnetic layer provided between the fixed layer and the recording layer and in which the magnetization directions of the fixed layer and the recording layer are brought into a parallel state or an anti-parallel state in accordance with a direction of a current flowing between the fixed layer and the recording layer; a first contact which is connected to the recording layer and in which a contact area between the recording layer and the first contact is smaller than an area of the recording layer; and a cap layer which is provided between the first contact and the recording layer and which directly comes in contact with the first contact and which has a resistance higher than a resistance of the recording layer; wherein an area of the first contact is equal to an area of the magnetoresistive effect element, and a center of the first contact shifts from a center of the magnetoresistive effect element, the contact area between the first contact and the recording layer is reduced.
