One or more processors determine a predicted sorting bin of a semiconductor device, based on measurement and test data performed on the semiconductor device subsequent to a current metallization layer. A current predicted sorting bin and a target sorting bin are determined by a machine learning model for the semiconductor device; the target bin include higher performance semiconductor devices than the predicted sorting bin. The model determines a performance level improvement attainable by adjustments made to process parameters of subsequent metallization layers of the semiconductor device. Adjustments to process parameters are generated, based on measurement and test data of the current metallization layer of semiconductor device, and the adjustment outputs for the process parameters of the subsequent metallization layers of the semiconductor device are made available to the one or more subsequent metallization layer processes by a feed-forward mechanism.

A non-volatile memory cell includes a thin film resistor (TFR) in series and between a top state influencing electrode and a top wire. The TFR limits or generally reduces the electrical current at the top state influencing electrode from the top wire. As such, non-volatile memory cell endurance may be improved and adverse impacts to component(s) that neighbor the non-volatile memory cell may be limited. The TFR is additionally utilized as an etch stop when forming a top wire trench associated with the fabrication of the top wire. In some non-volatile memory cells where cell symmetry is desired, an additional TFR may be formed between a bottom wire and a bottom state influencing electrode.
