two ways to handle it: Write Allocate (aka Fetch on Write) –datum at the Missed-write location are loaded to cache, followed by a write-hit opera tion. In the approach, write misses are similar to read-misses. No-write Allocate (aka Write-no-allocate, write around) –datum at the Missed-write location are not loaded to cache, and I s written directly to the backing store. In this approach, actually only s
