The Memory management unit consists of
Segmentation unit and
Paging unit.
Segmentation unit allows the use of two address components, viz. segment and offset for relocability and sharing of code and data.
•Segmentation unit allows segments of size 4Gbytes at max.
•The Paging unit organizes the physical memory in terms of pages of 4kbytes size each.
Paging unit works under the control of the segmentation unit, i.e. each segment is further divided into pages. The virtual memory is also organizes in terms of segments and pages by the memory management unit.
