Supposedly, they do not die; they simply fly back to their home planet. On the older tamagotchis, though, the Japense versions would show an animation of a ghost next to a grave when the tamagotchi "died."
When people are sad if their tamagotchi leaves/dies (however you look at it), they may contribute their tamagotchi's information to an online "graveyard" that someone created.
