Abstract
In a medical treatment device implanted within the body of a patient, a system and method using volatile and non-volatile memory devices within an implanted drug infusion pump to provide a safe and robust programmable system, able to back-up and restore the device's hardware and software operating parameters in the event of RAM corruption and as an alternative to hardware trim techniques. The pump includes a processor, a ROM, a RAM, and an EEPROM. The RAM serves as a main memory and the EEPROM serves a back-up memory in the event of RAM corruption. The ROM serves as an additional layer of back-up memory in the event of RAM and EEPROM corruption.
