ADDRESS BUS Definition from Encyclopedia Dictionaries & Glossaries

Wikipedia English - The Free Encyclopedia
Address bus
An address bus is a computer bus, used by CPUs or DMA-capable units for communicating the physical addresses of computer memory elements/locations that the requesting unit wants to access (read/write).

The width of an address bus, along with the size of addressable memory elements, determines how much memory can be accessed. For example, a 16-bit wide address bus (commonly used in the 8-bit processors of the 1970s and early 1980s) reaches across 216 = 65,536 = 64Ki memory locations, whereas a 32-bit address bus (common in today's PC processors) can address 232 = 4,294,967,296 = 4Gi locations.
