Abstract
Abstract A memory programming system which provides a method and apparatus for programming and reading an electronic device memory through its power source connections. Circuitry is provided for programming and reading internal EEPROM memory of a portable radio with information provided by an external programming apparatus through its existing battery terminals, wihout removing the EEPROM from the unit, and without the use of supplementary connectors. The radio battery is disabled and a substitute power source is connected to the existing battery terminals, the substitute power signal is encoded with program data by the programming apparatus circuitry and decoded by the radio circuitry, and a programming voltage is applied to the EEPROM such that the program data is programmed into the radio memory through the battery terminals. The program data can be verified by encoding the substitute power signal with verification data in the radio and decoding the signal externally to provide a visual indication for verification. The present invention may be used with any electronic device having a programmable memory that warrants field re-programming.
