Abstract
Domains can also be used to control access to physical memory space. Data in a physical memory space that has been used by a process sometimes endures after the process stops using the physical memory space (e.g., the process terminates). In addition, a virtual memory manager may allow processes of different applications to access a same memory space. To prevent exposure of sensitive/confidential data, physical memory spaces can be designated for a specific domain or domains when the physical memory spaces are allocated.
