Spice Model for Transient Analysis of EEPROM Cells

An equivalent model for the EEPROAM cell, described on a SPICE circuit analyzer. is used for the transient analysis of erase(E)/write(W) characteristics with ramp waveform programming pulses. The results of the simulation are compared with the experiemental data obtained by an innovative method for measuring E/W curves. The validation of the model is made over different variations of the cell lay-out, different programming voltages and diffrernt rise times for the ramp of the programming pulse.
