Abstract: A memory circuit for a print component including a plurality of I/O pads, including an analog pad, to connect to a plurality of signal paths which communicate operating signals to the print component. The memory circuit includes a controllable selector connected in line with one of the signal paths via the I/O pads, the selector controllable to disconnect the corresponding signal path to the print component, and a memory component to store memory values associated with the print component. A control circuit, in response to a sequence of operating signals received by the I/O pads representing a memory read, to operate the controllable selector to disconnect the signal path to the print component to block the memory read of the print component, and provide an analog signal to the analog pad to provide an analog electrical value at the analog pad representing stored memory values selected by the memory read.

Abstract: The present subject matter relates to an electrical programmable read only memory (EPROM) cell. The EPROM cell comprises a semiconductor substrate and a floating gate separated from the semiconductor substrate by a first dielectric layer. A control gate is capacitively coupled to the floating gate through a second dielectric layer disposed between the floating gate and the control gate. In an example, the EPROM cell further comprises a conductive gate connected to the floating gate, wherein the conductive gate is to leak charges from the floating gate in a predetermined leak time period.

Abstract: A fluid ejection device including a printhead die having a plurality of layers, including a single metal layer, and having an integrated ink level sensor. The ink level sensor includes an ink chamber above the metal layer, a metal plate of a sense capacitor disposed in the metal layer, and a clearing resistor circuit disposed in the metal layer including four clearing resistors arranged in a surround-4 configuration about the metal plate and electrically connected in parallel between a voltage potential and ground, wherein adjacent ends of at least two clearing resistors are not directly connected to one another so as to leave a gap between the adjacent ends in the metal layer. A metal lead in the metal layer extends through the gap to the metal plate.
