A 1.25µm2 cell 32Kb electrical fuse memory in 32nm CMOS with 700mV Vddmin and parallel/serial interface

This paper presents a highly optimized 32Kb electrical fuse memory in 32nm CMOS with 1.25µm2 small cell, the smallest cell ever published. This macro has low program current of 6mA at 2.5V for 0.5?µs, high-gain sense amplifier to achieve 700mV Vddmin, and parallel/serial interfaces for high density or low pin-count applications.
