What is a memory cache-write-hit-write-allocate?

A memory cache-write-hit-write-allocate is a cache memory operation where a write operation is performed on a cache line that is already present in the cache (write-hit), and if the cache line is not present, it is fetched from the main memory and then the write operation is performed (write-allocate).
