Editing Memory segmentation (section)

===Segmentation with paging===
Instead of a memory location, the segment information includes the address of a [[page table]] for the segment.
When a program references a memory location the offset is translated to a memory address using the page table. A segment can be extended by allocating another memory page and adding it to the segment's page table.

An implementation of [[virtual memory]] on a system using segmentation with paging usually only moves individual pages back and forth between main memory and secondary storage, similar to a paged non-segmented system. Pages of the segment can be located anywhere in main memory and need not be contiguous. This usually results in a reduced amount of input/output between primary and secondary storage and reduced memory fragmentation.
