What is a memory cache-write-no-allocate?

A memory cache-write-no-allocate is a cache write policy where, if a write operation is performed on a memory location that is not present in the cache, the data is not brought into the cache. Instead, the write operation is directly performed on the main memory. This policy helps to reduce cache pollution by avoiding unnecessary data transfers and updates in the cache.
