ABSTRACT:
In some embodiments, a comparator compares an incoming memory address with a memory address currently being copied by a memory copy operation. A holding buffer holds the incoming address prior to forwarding it to a memory read/write queue if the incoming memory address is the same as the memory address currently being copied by the memory copy operation, forwards the buffered incoming memory address to the read/write queue once the memory copy operation for the memory address currently being copied has finished. Other embodiments are described and claimed.
