internal data bus LastModified: Monday, November 10, 2003
A bus that operates only within the internal circuitry of the CPU, communicating among the internal caches of memory that are part of the CPU chip’s design. This bus is typically rather quick and is independent of the rest of the computer’s operations. Contrast with external data bus. The bit width of internal and external data buses are not always equal.
