Abstract
In accordance with the present invention, a non-volatile integrated circuit memory includes an EEPROM array comprising a plurality of memory cells and a flash EPROM array comprising a second plurality of memory cells, wherein the EEPROM array is capable of being erased byte-by-byte or word-by-word, and the flash EPROM array is capable of being erased sector-by-sector. Both arrays are formed using the same memory cell which is programmed using hot-electron injection and is erased using Fowler-Nordheim tunneling.
