An error detector for detecting storage errors, wherein the error detector comprises: - a low-voltage exit detector including: - a low-voltage detector for detecting a non-low-voltage condition of a watched voltage (Us), in which an absolute value (|Us|) of the watched voltage (Us) is higher than a threshold voltage (Uth), and for detecting a low-voltage condition (62, 63) of the watched voltage (Us), in which the absolute value (|Us|) is lower than the threshold voltage (Uth); and - a voltage rise detector for providing a trigger signal upon detection of a change from the low-voltage condition (62, 63) of the watched voltage (Us) to a non-low-voltage condition of the watched voltage (Us). - a first loader for loading a first loading information (248'a) into a first storage element, wherein the first loading information (248'a) is a supervised information coded using a first coding scheme; - a second loader for loading a second loading information (248'b) into a second storage element, wherein the second loading information (248'b) is the supervised information coded using a second coding scheme; - a first retriever for retrieving a first stored information (248"a) stored in the first storage element; - a second retriever for retrieving a second stored information (248"b) stored in the second storage element; - a comparator for comparing a combination of a first retrieved information (248"'a) retrieved using the first retriever and a second retrieved information (248"'b) retrieved using the second retriever to each encoding pattern of a set of valid patterns and for generating a match-mismatch signal indicating a result of this comparison; and - a trigger signal line for receiving a trigger signal from a low-voltage exit detector and at least one of a trigger function (520") for enabling the retrieval of the retrieved information (248'''a, 248"'b), a trigger function for controlling a generation of a comparison result, and an enable function (520"") for enabling an output of the match-mismatch signal only in case of receiving the trigger signal from the low-voltage exit detector. - a low-voltage exit detector including: - a low-voltage detector for detecting a non-low-voltage condition of a watched voltage (Us), in which an absolute value (|Us|) of the watched voltage (Us) is higher than a threshold voltage (Uth), and for detecting a low-voltage condition (62, 63) of the watched voltage (Us), in which the absolute value (|Us|) is lower than the threshold voltage (Uth); and - a voltage rise detector for providing a trigger signal upon detection of a change from the low-voltage condition (62, 63) of the watched voltage (Us) to a non-low-voltage condition of the watched voltage (Us). - a low-voltage detector for detecting a non-low-voltage condition of a watched voltage (Us), in which an absolute value (|Us|) of the watched voltage (Us) is higher than a threshold voltage (Uth), and for detecting a low-voltage condition (62, 63) of the watched voltage (Us), in which the absolute value (|Us|) is lower than the threshold voltage (Uth); and - a voltage rise detector for providing a trigger signal upon detection of a change from the low-voltage condition (62, 63) of the watched voltage (Us) to a non-low-voltage condition of the watched voltage (Us). - a first loader for loading a first loading information (248'a) into a first storage element, wherein the first loading information (248'a) is a supervised information coded using a first coding scheme; - a second loader for loading a second loading information (248'b) into a second storage element, wherein the second loading information (248'b) is the supervised information coded using a second coding scheme; - a first retriever for retrieving a first stored information (248"a) stored in the first storage element; - a second retriever for retrieving a second stored information (248"b) stored in the second storage element; - a comparator for comparing a combination of a first retrieved information (248"'a) retrieved using the first retriever and a second retrieved information (248"'b) retrieved using the second retriever to each encoding pattern of a set of valid patterns and for generating a match-mismatch signal indicating a result of this comparison; and - a trigger signal line for receiving a trigger signal from a low-voltage exit detector and at least one of a trigger function (520") for enabling the retrieval of the retrieved information (248'''a, 248"'b), a trigger function for controlling a generation of a comparison result, and an enable function (520"") for enabling an output of the match-mismatch signal only in case of receiving the trigger signal from the low-voltage exit detector.
