Abstract
An embodiment of the invention provides a sensing device. The sensing device includes a controller, a Resistive random memory sensor, an access circuit and a comparator circuit. The access circuit accesses the Resistive random memory sensor. The comparator circuit is coupled to the controller and the access circuit. The controller writes a predetermined data to the Resistive random memory sensor via the access circuit. After a predetermined condition, the access circuit reads a first data from the Resistive random memory sensor. The comparator circuit compares the first data with the predetermined data and transmits a comparison result to the controller. The controller determines whether an abnormal condition occurs based on the comparison result.
