Some embodiments show a storage circuit with fault detection. The storage circuit comprises, first and second fault detection circuits each comprising a first stable state and a second stable state, wherein each of the first and the second fault detection circuits is configured such that a fault signal strength necessary to cause switching from the first stable state to the second stable state is different from a fault signal strength necessary to cause switching from the second stable state to the first stable state. Furthermore the storage circuit comprises a data input, a circuitry configured to cause the first fault detection circuit to assume the first stable state and the second fault detection circuit to assume the second stable state to store a data signal applied to the data input and a first output indicative of the state of the first fault detection circuit and a second output indicative of the state of the second fault detection circuit, wherein an invalid combination of the signal states at the first and second outputs indicate a fault.
