Abstract :
A CAD EEPROM circuit model is essential to the design/optimization of low power non-volatile memory products. This paper presents a new FETMOS EEPROM circuit model that includes both Fowler-Nordheim and band-to-band tunneling. A DC model for FETMOS operation is derived and then extended to transient device operation. The model has been implemented into SPICE and applied to simulate the program/erase of a FETMOS bitcell and threshold voltage shifts under various bias conditions.<>
