Three dimensional memory |
| abstract |
A three dimensional memory using materials switchable from an amorphous state to a crystalline state and back again to its amorphous state is realized by focusing a laser beam into different depths of the material. The material, when in its crystalline state, is capable of generating the harmonic of the frequency of the incident light used to interrogate its state, whereas in its amorphous state it is not a generator of harmonics. The detection of this harmonic allows for increased discrimination in the data reading process. |
