Abstract

An updater device for flash read-only memory is provided. The updater device may be constructed using a power input interface that transfers battery from either a battery or an electrical adapter to the updater device. The updater device has a body containing circuitry that controls the operations of the device. Located in the body is an input, or first, port and an output, or second, port for engaging flash read-only memories. A source flash read-only memory is inserted into the input port and the updater is then placed over the target flash read-only memory so that the updater device engages the target flash memory. A button that is located on the body activates the updating process. First the microprocessor reads data from the source flash read-only memory via a first read-only memory interface located in the input port. Then the microprocessor uses a second read-only memory interface in the second port to erase the target read-only memory. Next, the microprocessor encodes the data read from the source flash memory onto the target flash memory. Before ending the updating process, the updater device confirms that the data encoded on the target flash read-only memory matches that previously read from the source flash read-only memory. During the updating process, the target flash memory is not removed from the attached printed circuit board. Light emitting diodes are attached to the body of the updater device to indicate the status of the updating process. After the newly encoded data on the target flash memory is confirmed a light emitting diode is activated to inform the user whether the target flash memory was properly encoded.
