Abstract: A non-volatile memory cell includes a tunneling part; a coupling transistor, including a coupling gate part, a first conductive region and a second conductive region, wherein the coupling gate part is coupled to the tunneling part and disposed in the first conductive region; a read transistor with a read gate part coupled to the tunneling part for forming an electron tunneling ejection path in an erase mode, and forming an electron tunneling injection path in a program mode; and a select transistor, connected in series with the read transistor, for forming a read path with the read transistor in a read mode.

Abstract: An audio-video synchronization detection device and a method thereof are provided. The audio-video synchronization detection device detects an object under test which is capable of generating an image signal and an audio signal. The audio-video synchronization detection device includes a delay circuit, an optical sensor, and a signal processor. The delay circuit delays the audio signal for a predetermined time and generates an audio correction signal accordingly. The optical sensor senses a light emitted by a display panel when the display panel displays the image signal and generates an image sensing signal accordingly. The signal processor calculates a delay time between the audio correction signal and the image sensing signal to obtain a synchronization state between the image signal and the audio signal.
