Embedded OTP fuse in CMOS logic process

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.
