data bus

   Also found in: Acronyms, Wikipedia 0.01 sec.
data bus
An internal pathway across which data are transferred to and from the processor or to and from memory. See local bus, system bus and peripheral bus.
data bus [′dad·ə ‚bəs]
(electronics)
An internal channel that carries data between a computer's central processing unit and its random-access memory.

(architecture)data bus - The bus (connections between and within the CPU, memory, and peripherals) used to carry data. Other connections are the address bus and control signals.

The width and clock rate of the data bus determine its data rate (the number of bytes per second it can carry), which is one of the main factors determining the processing power of a computer. Most current processor designs use a 32-bit bus, meaning that 32 bits of data can be transferred at once. Some processors have an internal data bus which is wider than their external bus in order to make external connections cheaper while retaining some of the benefits in processing power of a wider bus.

The data Bus is partly responsible for our clear and fast the graphics of our favorite games are displayed.
The addition of the triple data bus in a nine-layer MCP further demonstrates Toshiba's advanced packaging leadership and enables us to optimize overall performance of the memory subsystem, while giving our customers the flexibility to choose the type and density of memory they need to meet the requirements of today's and tomorrow's advanced multimedia- equipped cellular phones," said Scott Beekman, business development manager, communication memory products, for TAEC.
Also, in order to optimize data transfer between the CPU and MCP, Toshiba has adapted a "triple- data bus system" which consists of a high speed bus (for SDRAM and NOR), a middle speed bus (for SRAM and NOR) and NAND bus.
