Abstract: The present invention aims to provide a programmable device with a configuration memory that can hold the state of the occurrence abnormal situation that is difficult to assume such as a failure occurring in the programmable device due to the terrestrial radiation of the configuration memory, even during power off, in order to improve the reproducibility in device testing based on the held error information. The programmable device with the configuration memory includes: an error detection section for detecting an error in the configuration memory, and outputting the detected error as well as an address in which the error occurred, as error information; and an error information holding section provided with a non-volatile memory to store the output error information.
