A specific embodiment is disclosed for a method and apparatus for processing data access requests from a requesting device, such as a graphics processor device. Data access commands are provided at a first rate, for example 200M command per second, to a memory bridge. In response to receiving the access requests the memory bridge will provide its own access requests to a plurality of memories at approximately the first rate. In response to the memory bridge requests, the plurality of memories will access a plurality of data a second data rate. When the data access between the memory bridge and the memories is a read request, data is returned to the requesting device at a third data rate which is greater than the first data rate by approximately four times or more. Noise and power reduction techniques can be used on the data bus between the accessing device and the data bridge.
