ABSTRACT:
The present invention provides a memory cell which includes a pair of flash EEPROM cells. One flash EEPROM cell is programmed and the other flash EEPROM cell is simultaneously erased by a single programming pulse. Because the configuration memory cell includes flash EEPROM cells, and therefore is non-volatile, a power down does not require reprogramming or refreshing of the configuration bit stored in the memory cell.
