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:
“A man of sense, though born without wit, often lives to have wit. His memory treasures up ideas and reflections; he compares them with new occurrences, and strikes out new lights from the collision. The consequence is sometimes bons mots, and sometimes apothegms.”
—Horace Walpole (1717–1797)
“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)
