Write notes on associative mapping function related to cache memory.

The simplest technique for replacement policy in cache is called write through. Using this technique, all write operations are made to main memory as well as to the cache, ensuring that main memory is always valid. Any other processor-cache module can monitor traffic to main memory to maintain consistency within its own cache. The main disadvantage of this technique is that it generates substantial memory traffic and may create a bottleneck. An alternative technique, known as write back, minimizes memory writes. Discuss the term "write back".
