    Abstract: A non-volatile memory integrated circuit has a memory plane organized into rows and into columns containing bit lines. The read amplifiers for each bit line are configured to generate an output signal on a read data channel. The read data channels respectively run through the memory plane along each bit line. Each read data channel is connected to all of the read amplifiers of the respective bit line.

    Abstract: In accordance with an embodiment of the present invention, a method of making a semiconductor device includes simultaneously etching a semiconductor layer and a conductive layer to form a self-aligned diode region disposed on an insulating layer, where the semiconductor layer has a first conductivity type. The method further includes etching through first openings of a mask layer to form first implantation surfaces on the semiconductor layer and to form a plurality of projecting regions including conductive material of the conductive layer over the semiconductor layer. The method further includes using the plurality of projecting regions as a part of a first implantation mask, performing a first implantation of dopants having a second conductivity type into the semiconductor layer, to form a sequence of PN junctions forming diodes in the semiconductor layer. The diodes vertically extend from an upper surface of the semiconductor layer to the insulating layer.

    Abstract: In accordance with an embodiment, a physically unclonable function device includes a set of floating gate transistor pairs, floating gate transistors of the set of floating gate transistor pairs having a randomly distributed effective threshold voltage belonging to a common random distribution; a differential read circuit configured to measure a threshold difference between the effective threshold voltages of floating gate transistors of floating gate transistor pairs of the set of floating gate transistor pairs, and to identify a floating gate transistor pair in which the measured threshold difference is smaller than a margin value as being an unreliable floating gate transistor pair; and a write circuit configured to shift the effective threshold voltage of a floating gate transistor of the unreliable floating gate transistor pair to be inside the common random distribution.
