I-fuse: Most Reliable and Fully Testable OTP

Patented by Attopsemi™, I-fuse™ is a revolutionary non-breaking fuse technology that can be reliably programmed by heat assisted electromigration below a break point. Any cell can be tested as programmable if the initial fuse resistance is low enough (e.g. <400 ohms) to generate enough heat for programming.

I-fuse OTP - The OTP of Choice

OTP stands for “One-Time Programmable”, a device that can only be programmed once to permanently store any kind of information (data for chip IDs, security keys, product feature selection, memory redundancy, device trimming, or MCU code memory). Every chip needs OTPs, as long as they are reliable, available, and affordable.
