Paged Virtual Memory: Main Idea

• Divide memory (virtual and physical) into fixed size blocks (Pages, Frames).

  • Pages in Virtual space.
  • Frames in Physical space.

• Make page size a power of 2: (page size = 2k)

• All pages in the virtual address space are contiguous.

• Pages can be mapped into any physical Frame

• Some pages in main memory (DRAM), some pages on secondary memory (disk).
