Claim:
1. A memory element, comprising: (a) a memory layer having magnetization perpendicular to a film face of the memory layer and parallel to a thickness direction of the memory element in which a direction of the magnetization is changeable, the memory layer comprising two ferromagnetic material layers between which is a multilayer structure in which a non-magnetic layer and a non-magnetic oxide layer are in direct contact with each other, the direction of the magnetization of the memory layer being changeable by applying a current in the thickness direction of the memory element to record information in the memory layer, the two ferromagnetic material layers comprising a same ferromagnetic material and having the same direction of magnetization, (b) a magnetization-fixed layer having a fixed magnetization perpendicular to the film face and parallel to the thickness direction of the memory element, and (c) an intermediate layer comprising a non-magnetic material between the memory layer and the magnetization-fixed layer, wherein,
