I-fuse: Most Reliable and Fully Testable OTP
By Shine Chung, Chairman of Attopsemi™ Technology Abstract: OTP stands for “One-Time Programmable”, a device that can only be programmed once to store data permanently but ideally read infinite times. Traditionally, testability has been an issue for OTP. Every OTP bit should be programmed to ensure programmability. However, if only a single bit is programmed, the OTP block can no longer be used. 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...
