buffered write-through

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.
