Non-volatile latch circuits, such as in memory cells and flip-flops, that are constructed for reliability screening. The non-volatile latch circuits each include ferroelectric capacitors coupled to storage nodes, for example at the outputs of cross-coupled inverters. Separate plate lines are connected to the ferroelectric capacitors of the complementary storage nodes. A time-zero test of the latch stability margin is performed by setting a logic state at the storage nodes, then programming the state into the ferroelectric capacitors by polarization. After power-down, the plate lines are biased with a differential voltage relative to one another, and the latch is then powered up to attempt recall of the programmed state. The differential voltage disturbs the recall, and provides a measure of the cell margin and its later-life reliability.
