Disclosed is a programmable pulse width discriminator circuit operable to receive a set of parameters from a user and indicate when an input signal satisfies conditions set by the user-defined parameters. The channel region and the gate electrode are common between a first memory cell transistor including the first pair of sourcedrain regions and a second memory cell transistor including the second pair of sourcedrain regions. The foldable actuator can be foldable between an insertion configuration for placement through an access device without the aid of a grasper or applicator, and a deployed configuration for supporting the tissue retrieval bag in an open state. In one instance, the communications link is directionally configurable for reassigning input lanes to output lanes and output lanes to input lanes. The unit cell array reads and writes a plurality of data by inducing different channel resistance to the plurality of channel regions depending on polarity states of the plurality of ferroelectric layers.
