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:
“Beauty sat bathing by a spring,
Where fairest shades did hide her;
The winds blew calm, the birds did sing,
The cool streams ran beside her.
My wanton thoughts enticed mine eye
To see what was forbidden:
But better memory said Fie;
So vain desire was chidden—”
—Anthony Munday (1553–1633)
“It seemed a long way from 143rd Street. Shaking hands with the Queen of England was a long way from being forced to sit in the colored section of the bus going into downtown Wilmington, North Carolina. Dancing with the Duke of Devonshire was a long way from not being allowed to bowl in Jefferson City, Missouri, because the white customers complained about it.”
—Althea Gibson (b. 1927)
