Abstract

A method for preventing unauthorized access to information in a semiconductor device that is secured with a security protocol that uses a first portion of the information may include in response to a verified inaccessibility-inducing signal, unlocking safety lock circuitry which is operable to prevent unintentional activation of self-destruction in the semiconductor device, and initiating the self-destruction of at least a portion of the semiconductor device. A semiconductor device is configured to prevent unauthorized access to information available therein that is secured with a security protocol that uses a first portion of the information. The semiconductor device may include safety lock circuitry operable to prevent unintentional activation of self-destruction in the semiconductor device and control circuitry operable to unlock the safety lock circuitry and to initiate the self-destruction of at least a portion of the semiconductor device in response to a verified inaccessibility-inducing signal.
