  • Patent number: 11844158
    Abstract: A single channel-based multi-functional light emitting diode lamp driving system includes: first and second light source groups distinguished for each lamp function thereof; a single LED lamp driving module adjusting an input voltage to a voltage required for each lamp function and to apply it to the first and second light source groups; a switching module controlling on or off of the first and second light source groups; and a control module controlling light amounts of the first and second light source groups by performing time-division control on an on or off time of the switching module in conjunction with the LED lamp driving module, wherein the control module is configured to perform time division turn-on control on the first and second light source groups by controlling at least one of a current value applied to the first and second light source groups or a duty ratio thereof in a high-beam passing mode.

  • Publication number: 20100227469
    Abstract: A method of manufacturing a flash memory device. According to the invention, a floating gate can be formed and a distance between cells can be secured sufficiently by using one conductive layer without using a SA-STI process that cannot be applied to the manufacture process of high-integrated semiconductor devices. It is therefore possible to minimize an interference phenomenon between neighboring cells. Furthermore, an isolation film is etched after a photoresist film covering only a high-voltage transistor region is formed, or a gate oxide film is formed after a semiconductor substrate is etched at a thickness, which is the same as that of the gate oxide film of the high-voltage transistor region, so that a step between the cell region and the high-voltage transistor region is the same. Accordingly, the coupling ratio can be increased even by the gate oxide film of the high-voltage transistor region, which is thicker than the tunnel oxide film of the cell region.

  • Patent number: 7745284
    Abstract: A method of manufacturing a flash memory device. According to the invention, a floating gate can be formed and a distance between cells can be secured sufficiently by using one conductive layer without using a SA-STI process that cannot be applied to the manufacturing process of highly integrated semiconductor devices. It is therefore possible to minimize interference between neighboring cells.
