Abstract
An electronic device includes a syndrome decoder, an error insertion control circuit, and a failure detection circuit. The syndrome decoder generates an error insertion code from a write syndrome generated based on a write pulse. The error insertion control circuit inserts an error into an internal codeword according to the error insertion code based on a read pulse. The failure detection circuit compares the write syndrome with a read syndrome generated from the internal codeword to generate a failure detection signal.
