The disclosure relates to an integrated circuit comprising at least two memory cells formed in a semiconductor substrate, and a buried gate common to the selection transistors of the memory cells. In one embodiment, a digital media player with a simplified user interface is disclosed that, like an FM radio, allows a user to easily select a category of digital media for playback. The isolation regions have a portion within and a portion above the semiconductor region. A clutch coupled to the elongate shaft is configured to engage a respective generator, transferring energy from shaft rotation to the generator which produces electricity.
