segmentation of memory is possible through registers.this helps us to relocating the program easily . in multiprogramming environment,access rights can be easily be implemented with segments . also sharing of segments by different process is also possibe.

Advantages of memory segmentation
Allow the memory capacity to be 1Mb even though the addresses associated with the individual instructions are only 16 bits wide.
Facilitate the use of separate memory areas for the program, its data and the stack.
Permit a program and/or its data to be put into different areas of memory each time the program is executed.
Multitasking becomes easy
