Title: Semiconductor device

Abstract: The yield of a semiconductor device is improved which has a large-scale logic circuit or which has both a logic circuit and a memory. A basic circuit block is provided with an input/output circuit. A transmission line and a branch line connect the input/output circuits so that information can be exchanged through the input/output circuits between one basic circuit block and another basic circuit block. The memory in each basic circuit block or in each input/output circuit can be programmed from the outside to designate the destination of a signal. By thus changing the program in the memory, the transmission destination of a signal can be changed to give various functions efficiently with a limited circuit scale. Moreover, if a basic circuit block fails another basic circuit block substitutes for it to improve the yield drastically.
