As the processor speeds have increased in the last few years, so has the speed or bandwidth of the data busses between the microprocessors, memory, and the system controller chips. Several bus standards and there respective
signaling characteristics are now in use: GTL (Gunning Transceiver Logic) is used primarily for host CPU and the PCI/Memory Host Controller; SSTL
(Series Stub Terminated Logic) is used for Host Controller to main memory (DDR SDRAM) or RAMBUS (Reflective Wave Switching) is used as analternative for Host Controller to main memory (RDRAM).
