The memory bus is the computer bus which connects the main memory to the memory controller in computer systems. Originally, general-purpose buses like VMEbus and the S-100 bus were used, but to reduce latency, modern memory buses are designed to connect directly to DRAM chips, and thus are designed by chip standards bodies such as JEDEC. Examples are the various generations of SDRAM, and serial point-to-point buses like SLDRAM and RDRAM. An exception is the Fully Buffered DIMM which, despite being carefully designed to minimize the effect, has been criticized for its higher latency.
Famous quotes containing the words memory and/or bus:
“I regard a love for poetry as one of the most needful and helpful elements in the life- outfit of a human being. It was the greatest of blessings to me, in the long days of toil to which I was shut in much earlier than most young girls are, that the poetry I held in my memory breathed its enchanted atmosphere through me and around me, and touched even dull drudgery with its sunshine.”
—Lucy Larcom (1824–1893)
“David: All the reporters are on the bus.
Lucas: Okay, start the bus then. And drive them over a cliff.”
—Jeremy Larner, U.S. screenwriter, and Michael Ritchie. David (Chris Prey)
