Abstract
A magneto-optical memory interface includes: a memory cell structure having multiple allocated magnetic recording cells, a selection means configured to select an individual or a predetermined number of the multiple allocated magnetic recording cells of the memory structure, and configured for an electronic signal to be applicable thereto; and a light irradiation part configured to irradiate the predetermined number of the multiple allocated magnetic memory cells with an optical signal, wherein each of the magnetic recording cells is a magnetic recording cell whose sensitivity to changes in a magnetization state thereof increases in response to an irradiation light from the light irradiation part, and each of the magnetic recording cells is a magnetic recording cell whose magnetization state changes in response to an applied electrical signal resulting from selection by the selection means and the irradiation light from the light irradiation part.
