Latest Patents
Lim Eng Sin holds a patent for a Die Anti-Tampering Sensor. This sensor circuit and method are designed to defend against tampering with an integrated circuit die. The invention utilizes metal wire loops to safeguard the circuitry. These metal wire loops feature several via pairs along their length. One of the vias connects to a NAND gate that detects any break in a section of the metal wire loop. The second via is employed to periodically discharge the metal wire loop, removing residual charge in preparation for detecting any uncharged sections. An integrated circuit can incorporate one or more metal wire loops on top of the circuitry that needs protection. Each metal wire loop is equipped with one or more NAND gates, and the outputs of these gates can be fed into OR gates to generate an overall signal. This signal can activate an alarm or initiate other security actions, such as erasing electrically erasable programmable read-only memory (EEPROM).
