An EEPROM Supercell for Custom Standard Cell IC's

This paper will present a modular EEPROM supercell that provides a convenient means for adding small amounts of nonvolatile storage to standard cell designs. The nonvolatile bit is a single poly cell which places the storage node next to (rather than on top of) the control transistor and adds just one mask to the 3um P-well CMOS process that supports a diverse standard cell library consisting of digital and analog cells.
