I read in Wikipedia that there were two ways to achieve "memory protection"
- Access control lists
- "Traits" where a SUN processor used traits for pointer and the memory. That particular processor had hardware designed to control a program by using "traits" for the pointers and the memory. I'm looking for the technique of that SUN CPU. There's nothing about it reading the Wikipedia article about memory protection. I'm certain there was a Wikipedia article that mentioned it.
I don't find the article again. Is it possible that you can help me find the article or more information about the above techniques?
