This paper presents the embedded OTP fuse in standard CMOS logic compatible process without additional mask. The embedded OTP fuse can be programmed in 100/spl mu/s per byte and be accessed in 6ns for 32 bits at once. The 32-bit OTP fuse takes less than 0.0085mm/sup 2/ in 0.25/spl mu/m CMOS process and has 10-year data retention at 85/spl deg/C.
