摘要： A data processor controlled system for providing virtual memory comprising a data processor memory for storing a plurality of real memory pages, secondary storage unit and a memory management control unit for moving the real memory pages into and out of the secondary storage unit wherein each real memory page is respectively stored as a virtual memory page. The invention provides a system and method for deferred allocation of space for a real memory page in the secondary storage unit for recording the address of the space in a table having a plurality of table pages for recording the secondary storage addresses of each of said virtual memory pages. The system includes control unit responsive to the moving of a memory page into the secondary storage, and determining whether the initial table page for recording the address of the moved page is present in the data processor memory, the control unit further responsive to the determining unit for moving, without any external process interrupts, the initial table page into the data processor memory if the initial table page is not present, and the recording unit for recording the address of the moved page into the initial page.
