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:
“All water has a perfect memory and is forever trying to get back to where it was.”
—Toni Morrison (b. 1931)
“There was an old man from Darjeeling
Who got on a bus bound for Ealing.
It said at the door,
“Please don’t spit on the floor,”
So he carefully spat on the ceiling.”
—Anonymous.
