Abstract
An integrated circuit which provides an arrangement by which the source of voltage for erasing the flash EEPROM memory array is detected and, if the source is a charge pump, the current provided is held to a constant lower value while, if the source is an external high voltage source, then the current is allowed to flow freely without regulation except by the size of a field effect transistor device in the path from the source of voltage to the memory array. In this manner, the circuitry is adapted to function with either internal or external power sources without paying a performance penalty for either type of operation.
