Abstract: A method for detecting an error in reading a data, includes in a step a) storing a first copy of the data item in a first area of an electronic memory and storing of a second copy of the data item in a second area. Step b) includes reading values of the first and second copies of the data item and in step c) there is a comparison of the read values of the first and second copies of the data item. In step d) if the read values of the first and second copies are identical, then no error is detected. In step e) if the read values of the first and second copies are different, then the method includes repeating steps b) and c). In step f), if the values read in step e) are identical, then an error in the reading of the data item is detected and, otherwise, no error is detected.

Abstract: There is disclosed a method for detecting an error in the reading of a data item, this method includesa)storing a first copy of the data item in a first area of an electronic memory and storing of a second copy of the data item in a second area of an electronic memory. In Step b there is also included a Reading of the values of the first and second copies of the data item in the first and second areas respectively,In step c)here is a comparison of the read values of the first and second copies of the data item if the read values of the first and second copies are different, then the preceding steps b) and c) are repeated (78, 80), thenf) if the values read in the step e) are identical, then an error in the reading of this data item is detected (82) and, otherwise, no error in the reading of this data item is detected.

Abstract translation: 公开了一种用于检测数据项的读取中的错误的方法，该方法包括：a）将数据项的第一副本存储在电子存储器的第一区域中，并将数据项的第二副本存储在 电子存储器的第二区域。 在步骤b中，还包括分别读取第一和第二区域中的数据项的第一和第二副本的值。在步骤c）中，这里是第一和第二副本的读取值的比较 数据项，如果第一和第二副本的读取值不同，则重复前面的步骤b）和c）（78,80），然后f）如果步骤e）中读取的值相同，则错误 检测到该数据项的读取（82），否则检测到该数据项的读取中没有错误。
