Aspects of the technology described herein relate to ultrasound device circuitry as may form part of a single substrate ultrasound device having integrated ultrasonic transducers. A combiner may combine the output of the digital switching distortion canceller with a digital high switching distortion signal to generate a corrected output signal. The clock signal is also input to a single inverter whose output drives the flip-flops. Further, a semiconductor memory device, which is attachable and detachable relative to the host device and thereby portable, and relatively inexpensively obtainable, can be provided, and is directly insertable into a laptop personal computer to be used. One or more first trenches are formed to the sources and drains of the first gates by removing the second insulating material between the insulating mandrels. A conductive fill is disposed within the at least one via hole forming a hermetic seal and electrically conductive between the body fluid side and the device side.
