Summary:A circuit to detect and record the occurrence of a surge in the supply voltage applied to an integrated circuit includes a detection circuit for providing a control signal if a voltage surge is detected. The circuit also includes a high voltage circuit, which produces a high programming voltage from the supply voltage if a voltage surge is detected, and a memory cell. The detection circuit may include a capacitor divider bridge, a voltage source, and a comparator. The circuit is particularly advantageous for use with electrically programmable memories.
