To provide a quantum case memory filling the role of an optical memory for high density recording, quick recording and low recording energy.
A quantum case memory filling the role of a non-volatile memory furnishing the existance of electron or hole taking localized state in the quantum case is composed of a quantum case QD, barrier layers B encircling the quantum case QD so as to electrically separate the case QD from ambient elements as well as a Schottky junction formed on both surfaces of the barrier layers B as if holding the quantum case QD. At this time, the quantum case QD may be arranged quadratically or three-dimensionally. Furthermore, the electron or the hole is to be inputted, read-out and erased by irradiating the quantum case QD with light.
