A conditioning process for integrated circuits including floating-gate devices, such as floating-gate capacitors or transistors in analog or other circuits in which the devices are to be programmed to a specific level. Following initial programming of the floating-gate devices to a specific programmed level, the integrated circuits are subjected to a conditioning bake, followed by re-trim back to the initial programmed level. That portion of the charge at the floating-gate device that was weakly held is removed by the conditioning bake, while the re-trim replaces that charge with more strongly held (i.e., higher activation energy) programmed charge.
