    • One-time programmable (OTP) nonvolatile fuse memory cells are disclosed that do not require decoding or addressing for reading their data content. Each fuse memory cell has its content latched at its output and available at all times and can be used, for example, for code storage memories, serial configuration memories, and as individual fuse bits for ID (identification), trimming, and other post-fabrication System-on-Chip (SoC) customization needs. Means are also provided for temporary data storage for design testing, etc. In alternative embodiments, using two differentially programmed fuses in a single memory cell, the selection and programming circuitry are merged.
    • 公开了一次性可编程(OTP)非易失性熔丝存储器单元,其不需要用于读取其数据内容的解码或寻址。 每个保险丝存储单元的内容在其输出端被锁存并且始终可用,并且可以用于例如代码存储存储器,串行配置存储器,以及作为用于ID(识别),修整和其他后期处理的单个保险丝位。 制造片上系统(SoC)定制需求。 还提供了用于设计测试等的临时数据存储的手段。在替代实施例中,在单个存储器单元中使用两个差分编程的熔丝,合并选择和编程电路。
