Abstract

To achieve a flexible change in output capability of data signals in each of a plurality of input / output circuits while suppressing the scale of the input / output circuits, in a semiconductor device including a plurality of input / output terminals and the input / output circuits provided corresponding to the input / output terminals.SOLUTION: A semiconductor device includes a plurality of input / output terminals and a plurality of input / output circuits provided corresponding to the input / output terminals, respectively. The plurality of input / output circuits each include: at least one driver that output a data signal; a first switching circuit switching connection and no-connection between the driver and a corresponding input / output terminal; and a second switching circuit switching connection and no-connection between the driver and a driver included in other input / output terminal.SELECTED DRAWING: Figure 1
