What is a memory write-miss?

A memory write-miss refers to a situation in which a processor attempts to write data to a memory location, but the data is not present in the cache or main memory. This results in the processor having to fetch the data from a higher level of memory hierarchy, such as main memory or disk storage, before the write operation can be completed. Memory write-misses can lead to increased latency and decreased performance in a computer system.
