Graphics and Memory Controller Hub
North Bridge
The fast end of the hub, called the North bridge, contains the graphic and memory controller, and connects directly to the processor by way of 64- bit bus, called the Front Side Bus (FSB), System Bus or host bus.
Yes it is true that memory caching is a method used to store data or programs in SRAM for quick retrieval. The North Bridge is the faster end of the hub that contains the graphics and memory controller.
North Bridge and South Bridge. The North Bridge is the faster end of the hub containing the graphics and memory controller and connects to the system bus. The South Bridge is the slower end of the hub and contains the I/O controller hub. All I/O devices with the exception of display and memory are connected by the slower South Bridge.
which controller hub is known as the norhtbridge
The north and south bridge refer to the data channels to the CPU. The memory goes to CPU using the north bridge. And the mouse, keyboard, CD ROM, HDD, ext data flows to the CPU using the southbridge. The northbridge is the portion of the chipset HUB that connects faster I/O buses (for example, an AGP bus) to the system bus. Northbridge chip tends to be larger than the southbridge chip. The southbridge is the HUB that connects to slower I/O buses (for example, an ISA bus) to the system bus. The Northbridge and the Southbridge are known as the chipset on the motherboard. These set of chips collectively control the memory cache, external bus, and some peripherals. There is a fast end of the hub, and there is a slow end of the hub. The fast end of the hub is the Northbridge, containing the graphics and memory controller connecting to the system bus. The slower end of the hub is the Southbridge, containing the I/O controller hub.

Maybe you mean "northbridge"? in that case:The northbridge has historically been one of the two chips in the core logic chipset on a PC motherboard. The northbridge is the memory hub controller.
