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

A memory cache-write-hit-write-allocate-invalidate is a cache operation that occurs when a write operation is performed on a memory location that is already present in the cache and the cache is write-allocated and write-through. In this case, the cache is updated with the new data and the corresponding memory location is marked as invalid, indicating that it needs to be fetched again from the main memory when accessed in the future.
