摘　　要：基于传统反熔丝器件编程电路结构的基础上,提出了一种新颖的可正反编程反熔丝单元的电路结构。该电路包括寄存器寻址电路、正反向配置电路、编程驱动控制电路。利用生成的码流文件,通过正反向编程需要配置的反熔丝单元,可有效降低反熔丝单元编程后的阻抗,提高编程后的传输一致性和编程稳定性。仿真验证表明,该方法和传统的单向编程电路相比,提高了编程后反熔丝单元的可靠性。On the basis of traditional programming circuit structure based on anti-fuse device,a novel circuit structure of forward and backward programmable anti fuse unit is proposed,which includes register addressing circuit,forward and reverse configuration circuit,programming drive control circuit.Using the generated code stream file,through forward and reverse programming the anti-fuse unit to be configured,the impedance of anti-fuse unit after programming can be effectively reduced,the transmission consistency after programming can be improved,and the programming stability can be improved.Simulation results show that compared with traditional unidirectional programming circuit,this method improves the reliability of antifuse unit after programming.
