<p>There has been a problem of difficult cell layout in a double-cell system FLOTOX-type EEPROM design for miniaturization. A double-cell system FLOTOX type EEPROM is provided with a pair of floating gates (25a, 25b), two tunnel windows (30a, 30b), a common source (27), a common control gate (26) and select gates (29a, 29b), and a drain (28) is shared. Thus, the double-cell system FLOTOX type EEPROM designed to have high reliability and withstand voltage is provided.</p> |
