This principle is used in many occasions, not just in cache memory. It is worth noting that it was discovered during the "invention" of virtual memory. The principle is used to try to predict which address the processor wants next.

Some examples of applications are: cache memory, virtual memory, TLB and DRAM-FPM construction.

Cache memory known as reference cause can copy data and make it's as reference to other.

Cache memory is very small memory in comparison with Primary and Secondary.

If any value is present in a small memory, then it becomes helpful for CPU to find that particular value, that's why frequently accessible values are present in this cache memory.

And the phenomenon of accessing any frequently used value is known as Locality of Reference.

Locality of reference, also known as the principle of locality, is the phenomenon of the same value or related storage locations being frequently accessed.
