We present an investigation of the process of charging and discharging of the floating gate of thin oxide Flash EEPROMs based on a fully quantum mechanical approach to transport in the vertical direction. Our approach allows us to compute program, erase, and retention times as a function of the gate stack structure, and applied voltages.
