Abstract
In this paper, we design a 256-bit EEPROM IP using only logic process-based devices. We propose EEPROM core circuits, a control gate (CG) and a tunnel gate (TG) driving circuit, to limit the voltages between the devices within 5.5V; and we propose DC-DC converters : VPP (=+4.75V), VNN (-4.75V), and VNNL (=VNN/3) generation circuit. In addition, we propose switching powers, CG_HV, CG_LV, TG_HV, TG_LV, VNNL_CG, VNNL_TG switching circuit, to be supplied for the CG and TG driving circuit. Simulation results under the typical simulation condition show that the power consumptions in the read, erase, and program mode are $12.86{\mu}W$, $22.52{\mu}W$, and $22.58{\mu}W$ respectively. Furthermore, the manufactured test chip operated normally and generated its target voltages of VPP, VNN, and VNNL as 4.69V, -4.74V, and -1.89V.
