Abstract
Systems and methods for identifying a device using a programmable memory circuit having at least one partially blown fuse are described herein. A fluid ejection apparatus includes an electronic controller. The electronic controller is configured to determine a resistance associated with a partially blown fuse in a programmable memory circuit and to determine an identifier based on the resistance.
