Abstract:
A storage element with monitoring circuit, comprising a previous state information storage element configured to record a previous state of a monitored state information storage element, a state change indication unit having a clock input terminal coupled to the clock signal input interface, a state change indication unit being configured to generate a state change indication signal indicative of whether the monitored state information storage element shall have performed a state change by observing the data at a data input interface and a data output terminal, and a state change confirmation unit configured to generate a storage fault indicator by observing the data output terminal of the monitored state information storage element and the data output of the previous state information storage element and checking whether the result of this observation is in line with the state change indicator.
