Abstract
A semiconductor integrated circuit has a judgment circuit incorporated to determine whether or not an error correction function has operated. In particular, this enables detection of the operating condition of the error correction function in an integrated circuit with an error correction function incorporated, through the addition of a simple circuit, and in turn enables checking of whether the device was originally of good quality, or is one repaired by the addition of an error correction function to a defective device.
