Abstract
Apparatus is disclosed for buffering writes from a CPU to main memory, in which sequential write requests to the same address are gathered and combined into a single write request. The embodiment described does not permit gathering with the write request in the buffer which is next scheduled for action by the main memory bus controller, nor does it permit gathering with other than the immediately preceding write request. The invention is implemented using a plurality of buffer ranks, each comprising a data rank, an address rank, and a valid rank for indicating which bits or bytes of the data rank contain data to be written to memory.
