Abstract
In a circuit for detecting an abnormal operation of memory, an integrated circuit including the same and a method for detecting an abnormal operation, an abnormal operation of memory is detected before an error occurs in the integrated circuit of a micro-computer and the like due to data wrongly output from the memory, enhancing the reliability of the integrated circuit. More specifically, a circuit is provided for detecting an abnormal operation of memory and includes a delay circuit for delaying an output data of memory for a predetermined period of time and for outputting this data as a delay data; and a comparison circuit for outputting a noncoincidence signal in a case that the output data of the memory and the delay data as compared are not coincident with each other.
