The Latte hardware implements AMBA (possibly rev 2.0) compliant AHB buses for communication to/from the Starbuck's CPU and assorted on-chip hardware blocks (DMA, for example).
One of such blocks appears to be a customized memory controller that is responsible for several tasks such as DDR configuration, flushing memory to/from the AHB and employing a custom memory protection solution dubbed MEM_BLOCK.
This controller appears to be an extension of the one that was previously used on the Wii.
