  1. Check an internal table for this process to determine whether the reference was a valid or an invalid memory access.

  2. If the reference was invalid, we terminate the process. If it was valid, but we have not yet brought in that page, we now page it in.

  3. Find a free frame

  4. Schedule a disk operation to read the desired page into the newly allocated frame.

  5. When the disk read is complete, we modify the internal table kept with the process and the page table to indicate that the page is now in memory.

  6. Restart the instruction that was interrupted by the trap. The process can now access the page as though it had always been in memory.
