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:
“There are no stars to-night
But those of memory.
Yet how much room for memory there is
In the loose girdle of soft rain.”
—Hart Crane (1899–1932)
“If Rosa Parks had taken a poll before she sat down in that bus in Montgomery, she’d still be standing.”
—Mary Frances Berry (b. 1938)
