Static, low-voltage fuse-based cell with high-voltage programming

摘要

A fuse-based cell and method of operation are described. The method includes programming a fuse to have a programmed state using a programming voltage that is greater than a supply voltage and sensing the programmed state of the fuse using a sense device. The method also includes providing bias current to the sense device using a load and isolating the sense device and the load from exposure to a full potential difference between the supply voltage and the programming voltage during the programming of the fuse.
