An apparatus according to an embodiment of the present invention is disclosed. The apparatus includes a memory interface. The memory interface determines an access time of an original read request. The memory interface outputs a data ready signal when the access time of the original read request expires. An arbiter is coupled to the memory interface. The arbiter arbitrates access to the memory interface. A blocking unit is coupled to the memory interface. The blocking unit blocks a retry of the original read request from reaching the arbiter unit until the data ready signal is output by the memory interface. According to one embodiment of the memory controller a bus interface is coupled to the memory interface. The bus interface issues a deferred read signal to the device making the original read request upon receiving a signal from the arbiter.
