Disclosed are interface buses that facilitate communications among two or more electronic devices in standard mode and burst mode, and bus bridges from such buses to a memory unit of such a device. In one aspect, interface buses group the data lines according to groups of bits, and include group-enable lines to convey a representation of which groups of data lines are active for each data transfer operation. In another aspect, exemplary interface buses include burst-length lines to convey a representation of the number of data bursts in a burst sequence, thereby obviating the need to provide sequential addresses over the bus. Exemplary bus bridges are capable of interpreting the signals on the interface bus and transferring data bursts between the interface bus and one or more memory units within the device.
