Consider a per-process page table, e.g.

• each page table entry (PTE) contains
  • page status ... Loaded, IsModified, NotLoaded
  • frame number of page (if Loaded)
  • disk address of page if applicable (if Not Loaded)
  • ... maybe others ... (e.g. last accessed time)
• we need ⌈ProcSize /PageSize⌉ entries in this table
