Abstract: Based on the principle of electron migration, eFuse realizes the programming operation by fusing the fuse to change its resistance characteristics irreversibly. High reliability is the core goal of eFuse system and circuit optimization design. This paper starts with the working principle and failure mode analysis of eFuse, and then focuses on the system causes and processes affecting its reliability. Based on the comprehensive conventional circuit design, combined with the factors affecting reliability in various working modes and specific modules, finally, a set of targeted circuit design solutions are proposed.
Key words : Failure analysis eFuse reliability circuit design
