Methods for fabricating a printhead are described. In one embodiment, a method includes forming on a substrate using a single fabrication technique multiple resistors, some of the resistors to be used as heater resistors configured to eject fluid and some of the resistors to be used as storage resistors that store data, annealing the heater resistors, and intentionally not annealing at least one of the storage resistors, wherein the annealed storage resistors have a first state representing a first digital value and the unannealed storage resistors have a second state representing a second digital value, such that the values associated with the storage resistors can be read by an appropriate detection circuit.
