Ultra-small and ultra-reliable innovative fuses scalable from 0.35um to 28nm

I-fuse is a fuse-based technology having (a) 1R1D cell, (b) limited programming below a critical current, and (c) small cell to improve program efficiency to pass qualification at 300°C for 4,290 hours. Test structures consist of single 1R1D structure and mini-arrays are used to characterize (a) critical current, (b) diode characteristics, and (c) cell current distribution.
