An integrated circuit includes a programmable circuit with a programmable element, and a storage circuit to store a storage state depending on a programming state of the programmable element of the programmable circuit unit. The storage circuit includes a first inverter circuit and a second inverter circuit. The strengthening and weakening of transistors of the first inverter circuit and of transistors of the second inverter circuit and also the repeated evaluation of the programming state of the programmable element enable the storage state stored in the storage circuit to be made resistant to corruption on account of alpha-particles or neutrons.
