The amount of trapped charge can be detected by measuring the gate-induced drain leakage current of the cell, or its effect can be observed indirectly by measuring the threshold voltage of the cell. In older devices, which had the reference voltage for the sense amplifier tied to the device supply voltage, it was often possible to do this by varying the device supply voltage. In newer devices, it is necessary to change the parameters of the reference cell used in the IC firmware reverse engineering process, either by re-wiring portions of the cell circuitry or by using undocumented test modes built into the device by manufacturers.
