摘要:
The present invention provides a semiconductor device in which an EEPROM and an OTPROM are mounted on the same chip, a single power supply system is used, and both ROMS can be effectively used. Such a semiconductor device has the EEPROM region and the OTPROM region arranged on the same chip, and a control device which makes only the prescribed cell in either region of both regions EEPROM and OTPROM regions active.
