Abstract
A very small magnetic tunnel junction is formed on a semiconductor p-i-n diode. Spin-polarized current which is generated by circular polarized light or elliptically-polarized light, is injected into a free layer of the magnetic tunnel junction so that magnetization direction (two opposite directions) in the free layer is changed based on the information, whereby information is stored in the memory element.
