Dual-channel Memory
Dual Channel memory controllers are memory controllers where the DRAM devices are separated on to two different buses to allow two memory controllers to access them in parallel. This doubles the theoretical amount of bandwidth of the bus. In theory, more channels can be built (a channel for every DRAM cell would be the ideal solution), but due to wire count, line capacitance, and the need for parallel access lines to have identical lengths, more channels are very difficult to add.

Famous quotes containing the word memory:
“When he became all eye when one was present, and all memory when one was gone; when the youth becomes the watcher of windows, and studious of a glove, a veil, a ribbon, or the wheels of a carriage, when no place is too solitary, and none too silent.”
—Ralph Waldo Emerson (1803–1882)
