buffered write-through
     
         A variation of {write-through} where the
        {cache} uses a "write buffer" to hold data being written back
        to {main memory}.  This frees the cache to service read
        requests while the write is taking place.  There is usually
        only one stage of buffering so subsequent writes must wait
        until the first is complete.  Most accesses are reads so
        buffered write-through is only useful for very slow main
        memory.
