ABSTRACT:
Each of the memory cells forming a nonvolatile RAM comprises one floating-gate transistor and one capacitor. When the power source is turned on, storage of information is performed according to the amount of electric charge stored in each capacitor. When the power source is turned off, nonvolatile storage of information is performed according to the level of the threshold voltage of each floating-gate transistor.
