Various I/O interface technologies in today's PC platform are classified into four categories, (1) ASIC (memory Controller) from / to Main Memory, (2) MPU from /to ASIC (Memory Controller), (3) ASIC (Memory Controller) from / to ASIC (Graphic Controller) and (4) ASIC from / to Peripherals. As to Category 1, effectiveness of SSTL is shown in DIMM application of SDRAM and DDR SDRAM over 100 MHz frequency. Furthermore a comparison is made between SLDRAM and D- RDRAM from the technology point of view. Concerning Categories 2 through 4, several interfaces such as PCI, AGP, GTL, HSTL and LVDS are reviewed. Interface technologies will keep playing an important role since computer systems require higher and higher speeds.
