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.
