摘　　要：在传统的基于反熔丝可编程逻辑阵列结构的基础上,提出一种新颖的寻址编程方法。该方法通过增加额外的编程支路,减小反熔丝单元被编程后的电阻;编程前,对所有布线通道进行预充电,防止反熔丝单元被误编程。仿真和测试结果表明,与传统的编程方式相比,该方法提高了编程的可靠性。A novel method for addressing and programming was presented based on conventional antifuse-based programmable logic array structure.In this method,resistance of programmed antifuse was reduced by additional programming branches.Before programming,a ＂pre-charge cycle＂ to all routing channels was performed to avoid misuse of antifuse programming.Both simulation and test results showed that the proposed method improved the reliability of programming,compared with conventional methods.
