Abstract
The buffer device array includes plural buffer devices connected to a bus, wherein the buffer devices hold the respective device addresses and device selection signals in the course of a data transfer operation and subsequently the device addresses and device selection signals held in the devices are used for inspecting devices with respect to whether they can be used for the next data transfer operation, thus enabling the data transfer operation and checking of device status for the next data transfer to be performed in a pipeline fashion and significantly increasing the efficiency of the data transfer operation and of the overall bus utilization.
