Abstract
An integrated circuit having an option between two or more configurations and also using a patterned ion-implant for impressing data (such as a ROM section of the circuit) may advantageously perform the option-specification simultaneously with the ROM; using a powerless option-specifying circuit permits testing portions of the circuit before the implantation step.
