Latest Patents

John Robert McDonald holds a patent for a "Nonvolatile memory implementation for electronic devices." This invention involves an automobile equipped with an electronic device that features a nonvolatile memory implementation. The electronic device comprises non-programmable nonvolatile memory (ROM), volatile memory (RAM), and programmable nonvolatile memory (EEPROM). The controller (CPU) manages the reads and writes to and from the ROM, RAM, and EEPROM. Upon detecting a key-off event, the CPU calculates an error recovery code (checksum) for a data string stored in the RAM and saves both the checksum and data into one of two memory locations in the EEPROM. The CPU alternates between these memory locations with each cycle. When a key-on event is detected, the CPU recalculates the checksum for the data string in the RAM. If the data string is invalid or the validity of the EEPROM data cannot be confirmed, the CPU retrieves a predetermined data string from the ROM to the RAM. If the calculated KAM checksum does not match the stored KAM checksum, the CPU copies the EEPROM data string to the KAM. Otherwise, the RAM data string remains unchanged.
