A method and apparatus for negative wordline decoding in a flash EEPROM (10) is provided. In particular, a predecoder (26) generates a predecoding signal based on address and invert inputs. The predecoding signal is used to select wordlines in both positive and negative voltage decoding modes. Each wordline...http://www.google.com/patents/US5311480?utm_source=gb-gplus-sharePatent US5311480 - Method and apparatus for EEPROM negative voltage wordline decoding
