Like on some flash games, if you do a memory scan for a specific value and you find it. If you reload the game or refresh your browser the address for that value will now be completely different. Most programmers will do this to help prevent hackers from making trainers / cheat devices.

What i’m wanting to know is what is the computing term for memory address’s that are randomly placed after each refresh / start-up ?
