Abstract
According to at least one embodiment, a method comprises measuring drive current of a reference memory cell of a circuit, and determining, based on the measured drive current of the reference memory cell, a drive current to be supplied to a calibration memory cell of the circuit to mimic a defective memory cell. The method further comprises supplying the determined drive current to the calibration memory cell, and using the calibration memory cell to determine strength of a weak write to be utilized by a weak write test for detecting defective memory cells.
