Abstract

PURPOSE: To make high-density recording and reproduction possible with simple constitution by recording and reproducing signals via a scanning electrode by using as recording medium an MNOS transistor equipped with a beltlike source, drain and gate.
CONSTITUTION: In N-type silicon semiconductor substrate 21, P-type impurity layer P and beltlike source 22 and drain 23 of diffused P are formed. Overlapping with those source 22 and drain 23, silicon oxide film 24 and silicon nitride film 25 of fixed thickness are vapor-deposited to obtain an MNOS transistor with a gate of beltlike film 25. When beltlike film 25 forming the gate is scanning by scanning electrode 27 applied with a positive voltage equivalent to data imformation with substrate 21 grounded, electrons are trapped by film 25 on the drain 23 side through the tunnel effect to shift the threshold level and the state that an inversion layer is formed in film 25 on the source 24 side is remembered even after the scan, thereby writing information. A read is similarly carried out and the simple constitution requiring no need for a connection wire, etc., attains high-density recording and also reproduction.
