Abstract: A locking system for an integrated circuit (IC) chip can include an arrangement of one or more antifuse devices in a signal path of the IC chip. The antifuse devices can be configured to operate in a first state, corresponding to a normally open switch, to inhibit normal operation of the IC chip, and to transition from the first state to a permanent second state, corresponding to a closed switch, in response to a program signal applied to at least one terminal of the IC chip to enable the normal operation of the IC chip.

Abstract translation: 用于集成电路（IC）芯片的锁定系统可以包括在IC芯片的信号路径中的一个或多个反熔丝器件的布置。 反熔丝装置可以被配置为在对应于常开开关的第一状态下操作，以阻止IC芯片的正常工作，并响应于闭合的开关从第一状态转变到永久的第二状态 涉及施加到IC芯片的至少一个端子的程序信号，以使IC芯片正常工作。
