An apparatus for improving bandwidth for circuits having a plurality of memory controllers employing a first memory controller, a second memory controller, a first busy read output signal circuit, a first busy write output signal circuit, a second busy read output signal circuit, and a second busy write output signal circuit. The first busy read output signal indicates when the first memory controller releases the address bus for a next external access subsequent to a read access to the data bus by the first memory controller. The first busy write output signal indicates when the first memory controller releases the data bus for a next external access subsequent to a write access to the data bus by the first memory controller. The second busy read output signal indicates when the second memory controller releases the address bus for a next external access subsequent to a read access to the data bus by the second memory controller. The second busy write output signal indicates when the second memory controller releases the data bus for a next external access subsequent to a write access to the data bus by the second memory controller.
