A DC-DC converter for EEPROM IPs which perfom erasing by the FN (Fowler-Nordheim) tunneling and programming by the band-to-band tunneling is designed in this paper. For the DC-DC converter for EEPROM IPs using a low voltage of 1.5V¡¾10% as the logic voltage, a scheme of using VRD (Read Voltage) instead of VDD is proposed to reduce the pumping stages and pumping capacitances of its charge pump circuit. VRD (=3.1V¡¾0.1V) is a regulated voltage by a voltage regulator using an external voltage of 5V. The designed DC-DC converter outputs VPP (=8V) and VNN (=-8V) in the write mode.
