Abstract

The use of Electrically Erasable Programmable Read Only Memory (EEPROM) allows firmware to be upgraded in the machine without physically replacing the device that contains that firmware. A problem with the current technology is that the EEPROM itself contains the code that is necessary to reprogram itself. If power fails while the EEPROM is being reprogrammed, only part of the EEPROM is programmed and there will be a mix of old and new firmware making the EEPROM unusable.
