An efficient method for the simulation of EPROM programming, based on hydrodynamic calculations of electron energy within the device, is described. After the nonMaxwellian energy distribution is calculated, an expression for injected gate current is integrated to find the total gate charge, and hence the threshold voltage shift, as a function of time. Comparison of theoretical and experimental results for actual EPROM programming validates this method.
