Yamaha has produced many of the integrated circuit chips for Sega arcade and console hardware, such as the YM2612 sound chip for the Sega Mega Drive console. Yamaha held the patent for FM synthesis, which was featured in many Yamaha synthesizers and sound chips, while some of their sound chips also featured PCM sampling. In addition, Yamaha also manufactured VDP graphics processors for the Sega Master System and Mega Drive consoles.
