PROBLEM TO BE SOLVED: To provide a reconfigurable device which prevents the occurrence of bus fight by stopping the output to a bus on the occurrence of error in configuration information memories. SOLUTION: The reconfigurable device includes a bus (102) for mutually connecting function blocks (101), configuration information memories (103) disposed correspondingly to function blocks, error detection circuits (105) for detecting errors of configuration information memories, and buffers (109 and 110) which are controlled to be turned on/off on the basis of information stored in the configuration information memories and control connections between function blocks and the bus. When an error of a configuration information memory (103) is detected by an error detection circuit (105), buffers (109 and 110) of which the outputs are connected to the bus are turned off on the basis of the error detection results.
