Answer - A - The internal data channel in a Rambus enables it to operate at speeds higher than that of a conventional 64-bit memory bus.

Key Takeaway: Rambus uses an internal 16-bit data channel that operates in conjunction with a 400 MHz clock. This allows the Rambus to operate at much higher speeds than more conventional 64-bit memory buses. A prime requirement with using Rambus memory is that all memory slots in the motherboard must be populated.
