  • Publication number: 20240147734
    Abstract: Various embodiments of the present disclosure are directed towards an integrated chip including a memory cell overlying a substrate and comprising a top electrode. A sidewall spacer structure is disposed along sidewalls of the memory cell. The sidewall spacer structure comprises a first spacer layer on the memory cell, a second spacer layer around the first spacer layer, and a third spacer layer around the second spacer layer. The second spacer layer comprises a lateral segment adjacent to a vertical segment. The lateral segment abuts the top electrode and has a top surface aligned with or disposed below a top surface of the top electrode. A first conductive structure overlies the memory cell and contacts the lateral segment and the top electrode.

  • Publication number: 20070061830
    Abstract: In accordance with one aspect of the present invention, a method determines whether a display device is being watched. A sound is emitted from the display device that is playing a content, and the sound is detected at a sensor that is distinct from the display device. A determination whether the display device is being watched is based upon whether the sound that is detected at the sensor compares favorably with the content. In accordance with another embodiment of the present invention, a set top box determines whether a display device is being watched. The set top box comprises an output (containing a sound) to provide content to a display device, a first input to receive an electronically readable signal corresponding to the sound from a sensor that is distinct from the display device, and a processor to determine whether the display device is being watched based upon whether the electronically readable signal compares favorably with the content.
