The mechanic is simple. We have the classic game Memory - in different editions and variations: http://www.boardgamegeek.com/geeksearch.php?action=search&objecttype=boardgame&q=memory&B1=Go. Here the mechanic is almost the only thing worth focusing on; the needed competences are obvious..
In many card games (Bridge etc) a mechanic like memory is also existing, you have to remember specific cards or colours.
In boardgames this mechanic is often existing, but in a much less degree. In a popular game like Settlers, you will be better of, if you remember how many specific ressources are in play, when you use the monopoloy-card. Just to name an example, where memory plays a small, but important role in the specific situation.
