ABSTRACT:
A memory element including a memory layer that retains information based on a magnetization state of a magnetic material is provided. In the memory element, a magnetization pinned layer is provided for the memory layer through an intermediate layer, the intermediate layer is formed of an insulator, spin-polarized electrons are injected in a stacking direction to change a magnetization direction of the memory layer, so that information is recorded in the memory layer. Also, a ferromagnetic layer forming the memory layer has a magnetostriction constant of 1×10−5or more.
