  • Publication number: 20240088246
    Abstract: Various embodiments of the present application are directed towards a control gate layout to improve an etch process window for word lines. In some embodiments, an integrated chip comprises a memory array, an erase gate, a word line, and a control gate. The memory array comprises a plurality of cells in a plurality of rows and a plurality of columns. The erase gate and the word line are elongated in parallel along a row of the memory array. The control gate is elongated along the row and is between and borders the erase gate and the word line. Further, the control gate has a pad region protruding towards the erase gate and the word line. Because the pad region protrudes towards the erase gate and the word line, a width of the pad region is spread between word-line and erase-gate sides of the control gate.

  • Patent number: 11318844
    Abstract: An on-board charging device includes an AC connector, an AC to DC converter and a detection circuit. The AC connector is configured to be connected to an electric vehicle supply equipment (EVSE), so that a protective earth terminal of EVSE is electrically connected to a protective earth terminal of the on-board charging device. The AC to DC converter is electrically connected to the AC connector, and the AC to DC converter is configured to convert an AC voltage provided by the EVSE into a DC voltage. The AC to DC converter has a reference ground terminal. The detection circuit outputs a detection voltage based on the voltage difference between the protective earth terminal of the on-board charging device and the reference ground terminal of the AC to DC converter. The detection voltage reflects whether the protective earth terminal of the EVSE is abnormal or not.
