Techniques for testing a semiconductor memory device are provided. The memory device includes a plurality of memory cells and a plurality of row lines and column lines connected to the memory cells for selectively accessing one or more of the memory cells. The method includes the steps of: applying a first voltage to at least a given one of the row lines corresponding to at least a given one of the memory cells to be tested, the first voltage being selected to stress at least one performance characteristic of the memory device, the first voltage being different than a second voltage applied to the given one of the row lines for accessing at least one of the memory cells during normal operation of the memory device; exercising the memory device in accordance with prescribed testing parameters; and identifying whether the memory device is operable within prescribed margins of the testing parameters.
