Abstract
A non-volatile ferroelectric latch includes a sense amplifier having at least one input/output coupled to a bit-line node, a ferroelectric storage capacitor coupled between a plate-line node and the bit-line node, and a load element coupled to the bit-line node. The sense amplifier further includes a second input/output coupled to a second bit-line node and the latch further includes a second ferroelectric storage capacitor coupled between a second plate-line node and the second bit-sine node, and a second load element coupled to the second bit-line node. The load element includes a dynamic, switched ferroelectric capacitor a static, nonswitched ferroelectric capacitor, a linear capacitor, or even a resistive load.
