ABSTRACT:
A method for updating the content of EEPROM memory used for controlling processes run on a microprocessor used to control the operations of a long term memory array which includes moving an update process stored in the EEPROM memory to a random access memory associated with the microprocessor; and then using the update process stored in random access memory for erasing the contents of the EEPROM memory, and furnishing data to the microprocessor on a sector by sector basis from a host computer through an interface used by the microprocessor to provide data to the long term memory array. The data furnished by the host is written sector by sector to the EEPROM memory until the EEPROM memory has been updated.
