Abstract
A semiconductor device including an electronic circuit, a memory, and an error detecting module. The electronic circuit is configured to receive an input signal having been generated by a test module, and generate an output signal based on the input signal. The memory is configured to store a predetermined output value that is expected to be output from the electronic circuit based on the electronic receiving the input signal, wherein the predetermined output value is stored in the memory prior to the input signal being generated by the test module. The error detecting module is configured to (i) generate a sample value of the output signal, (ii) compare the sample value of the output signal to the predetermined output value stored in the memory, and (iii) generate a result signal that indicates whether the sample value of the output signal matches the predetermined output value.
