ABSTRACT:
A method and system for processing multiple requests for data residing at the same memory address. The multiple requests are associated with an individual duplicate bit flag that indicates whether the request can be processed. Thus, manipulation of the duplicate bit flag controls the order of processing for each of the received requests, thereby maintaining data coherency and integrity.
