page fault
<memory management> In a paged virtual memory system, an access to a page
(block) of memory that is not currently mapped to physical memory. When a page
fault occurs the operating system either fetches the page in from secondary
storage (usually disk) if the access was legitimate or otherwise reports the
access as illegal.
