Magnetic semiconductor memory and the reading method using spin-polarized electron beam

摘要

A system for writing data to and reading data from a magnetic semiconductor memory utilizing a spin polarized electron beam. The magnetic semiconductor memory comprises a plurality of storage locations, each storage location includes a magnetic material and a layer of semiconductor material capable of emitting photons. The method of reading data from the magnetic semiconductor memory comprising steps of directing a spin-polarized electron beam at the magnetic semiconductor memory, and detecting the light emission state of the semiconductor layer from the magnetic semiconductor memory.
