Logic embedded one-time programmable (OTP) memory is extensively used for code storage, parameter settings, memory redundancy, and circuit trimming. With the explosive growth in Internet-of-Things application, different types of OTP cell, such as fuse, antifuse, and charge storage OTP have been developed. Among the above, antifuse OTPs have become one of the mainstream solutions for advanced logic circuits because of their small cell size, full compatibility, and good reliability. For achieving high-density data storage, antifuse OTP cell size also need be optimized. |
