write buffer - Free On-line Dictionary of Computing (26 May 2007) :

  buffered write-through
  write buffer
  
     <memory management> 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.
