A MTM Antifuse PROM Bitcell With a High Reliability for Satellite Use

In this paper, a novel MTM anti-fuse PROM bitcell with a high reliability is proposed, which can be used in stars and other spacecrafts. Based on this bitcell, programming and verification methods are studied. The use in PROM of the bitcell with the programming method described in this paper, can offer an effective protection to unselected anti-fuses in the programming process, therefore the reliability and working life of the PROM are improved.
