Abstract
Provided is a programmable logic integrated circuit wherein even if a failure occurs in any resistance-variable element, remedy would be possible and hence the improvement of reliability has been achieved. In a programmable logic integrated circuit comprising resistance-variable elements, when the states of the resistance-variable elements are to be changed according to externally inputted configuration information, a control means uses a reading means to read the states of the respective resistance-variable elements, and then uses a writing means to change only the states of resistance-changing elements that are different from a state indicated by the configuration information.
