Abstract
In a semiconductor chip for an electronic device, a programmable trim code is independent from a default trim code. An output trim code is produced by selecting either the default trim code or the programmable trim code. The default trim code for a plurality of the semiconductor chips is set by forming metal interconnects according to a first metal layout in a metal interconnect layer during fabrication of at least one of the semiconductor chips. The default trim code is reset by forming the metal interconnects according to a second metal layout in the metal interconnect layer during fabrication of subsequent semiconductor chips.
