摘　　要：由于工艺、制造和环境等原因,电编程熔丝(eFUSE)存储的数据信息可能发生意外改变,需要通过专门设计对数据进行冗余备份或对失效数据位进行修正,前者是对2个互为冗余的数据位进行相同编程操作,多用于eFUSE的现场编程;后者对失效数据位的修正大多采用的是串行冗余修正模式,但由于其存在延时随失效位数目增加的问题,一种以同步方式修正失效数据位的并行解决策略被提出并实现验证。Due to factors such as process,manufacturing,and environment,the data stored in the electrical programming fuses(eFUSEs)may undergo unexpected changes,requiring specialized design for data redundant backup or failure correction.The former performs the same programming operation on two mutually redundant data bits,which is commonly required in on-site programming of eFUSE.The latter correction of failed data bits mostly adopts the serial redundancy correction mode,but since the operation delay increases with the number of failed bits,a parallel solution strategy of synchronously correcting failure bits is proposed and implemented for validation.
