The patent describes a system and method for generating a random bit string in an integrated circuit using One-time Programmable Memory (OTPM) devices. These devices are connected in parallel and a predefined voltage is applied to cause a breakdown in one device, resulting in a random bit string based on the state of the broken and unbroken devices.
