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

A memory cache-write-miss-allocate refers to a situation in which a write operation is performed on a memory location that is not currently present in the cache. In this case, the cache needs to allocate a new cache line to store the data being written. This process involves evicting an existing cache line, if necessary, to make space for the new data.
