چکیده
−A 3-Transistor cell CMOS OTP ROM array using standard CMOS antifuse (AF) based on permanent breakdown of MOSFET gate oxide is proposed, fabricated and characterized. The proposed 3-T OTP cell for ROM array is composed of an nMOS AF, a high voltage (HV) blocking nMOS, and cell access transistor, all compatible with standard CMOS technology. The experimental results show that the proposed structure can be a viable technology option as a high density OTP ROM array for modern digital as well as analog circuits.

Review of fuse and antifuse solutions for advanced standard CMOS technologies
Specific applications require large amounts of high-performance, dense and low-cost non-volatile memories with CMOS standard process compatibility. There exists numerous structures for one-timeprogramming (OTP) bitcells, exploiting various physical phenomena as programming modes. Not all of these physical phenomena will behave in a satisfactory manner with the CMOS technology shrink. Moreover, ...
