Based on write-back method combined with the whole writing of the write strategy, write hits and write misses and write-back approach is basically the same method, only the first hit when writing to write also the main deposit. This is all easy to maintain cache coherence system.

Write the first method is based on the write-back method combined with the whole writing of the write strategy, write hits and write misses and write-back approach is basically the same method, only the first hit when writing to write also the main deposit. This is because the mystery when a write cache hit, CPU to start a store on the bus write cycle, the other listening to this cache and main memory block address signal, you can copy the block or time _set_ aside for all the cache consistency maintenance system sex. Pentium CPU chip data cache to write a law adopted.
