A multiple bit SP-vector is made to record each page history of the processor. Each time the teenager scans the accessed / not accessed bit flag of the page table entry, the SP-vector is updated to indicate whether the corresponding page has been accessed. Thus, depending on the number of bits in the SP-vector, a history of past use is created, and pages may be selected for swapping out of physical memory, based at least in part on this history.
