It happens to me too. Usually when you have multiple apps that consume large amounts of RAM, iOS will use the RAM used by other apps, usually apps that have been backgrounded more than 10 minutes. In severe cases it might stop active apps but I don't know enough about how iOS works to say with any certainty.

Just make sure you close apps before launching any memory intensive games or apps. There's no way to automatically "secure" parts of RAM from being modified or overwritten. The best way to manually "secure" them is to keep your memory usage low until you're done with anything that took time (writing a post in Safari, perhaps).
