  • Patent number: 7746705
    Abstract: A memory device comprising an optimization component that facilitates erasing memory cells in a substantially homogeneous electromagnetic field and methods that facilitate erasing memory cells in a substantially homogeneous electromagnetic field are presented. The optimization component facilitates selecting a subset of memory cells to be erased at the same time, such that a memory cell in the subset of memory cells has two neighbor memory cells adjacent thereto that are in the subset of memory, or one neighbor memory cell adjacent thereto when the memory cell is an end-row memory cell. The optimization component facilitates performing a Fowler-Nordheim channel erase to erase the subset of memory cells, and a predetermined voltage potential associated with an erase command is applied to each cell of the subset of memory cells to facilitate reducing fringing effect associated with the electromagnetic fields applied to the cells during the erase.

  • Patent number: 7733307
    Abstract: An emission driver for an organic light emitting display device is disclosed. The emission driver includes a plurality of flip-flops, and each flip-flop selectively receives two input signals and inverts a level of a received input signal. Also, each flip-flop transmits the level-inverted signal to an adjacent flip-flop, inverts the level-inverted signal, and transmits the inverted level-inverted signal to the adjacent flip-flop and as an emission control signal. To invert the level of the received input signal, the emission driver includes a level shifter, which includes transistors of the same conductivity type arranged to reduce power consumption.

  • Publication number: 20100103732
    Abstract: A system and methodology that can minimize disturbance during an AC operation associated with a memory, such as, program, read and/or erase, is provided. The system pre-charges all or a desired subset of the bit lines in a memory array to a specified voltage, during an AC operation to facilitate reducing AC disturbances between neighboring cells. A pre-charge voltage can be applied to all bit lines in a block in the memory array, or to bit lines associated with a selected memory cell and neighbor memory cells adjacent to the selected memory cell in the block. The system ensures that source and drain voltage levels can be set to desired levels at the same or substantially the same time, while selecting a memory cell. This can facilitate minimizing AC disturbances in the selected memory cell during the AC operation.

  • Patent number: 7659569
    Abstract: A memory device comprised of a plurality of memory cells that can each include multiple charge storage elements in undercut regions that are formed under a tunneling barrier and adjacent to a gate oxide layer of each memory cell.

  • Publication number: 20100027294
    Abstract: An optical sheet includes a base film in which light is incident from a lower side, a plurality of prism patterns and a diffusion member. The prism patterns are protruded to be spaced apart from each other on the base film to enhance the front luminance of light incident from the lower side of the base film. The diffusion member is disposed between prism patterns to have a diffusion surface in parallel with the base film. The diffusion member includes a plurality of diffusion dots capable of enhancing the luminance uniformity of light incident from the lower side of the base film. Thus, front luminance and luminance uniformity may be enhanced due to a juxtaposition of the prism patterns and the diffusion portion, and the viewing angle of the LCD device may be enhanced.

  • Patent number: 7626869
    Abstract: Erasing wordlines at the same time can cause undesirable results because some wordlines are affected by electromagnetic waves of other wordlines. However, other wordlines are not affected because they are next to contacts. Therefore, it can be beneficial to erase wordlines in a multi-phase sequence that allows for erasing wordlines without an impact from other wordlines.

  • Patent number: 7623097
    Abstract: An organic light emitting display (OLED) device using a tiling technique including a system-on-panel (SOP)-type emission control driver. The emission control driver includes a shift register and a logical operation portion having a plurality of logic gates, each of which receives output signals from the shift register and performs a logical OR operation on the received signals. An active load of each of the logic gates is controlled using two output signals and two inverted output signals of two adjacent flip-flops. Also, each of the logic gates performs a logical OR operation on the two output signals of the two adjacent flip-flops and generates an emission control signal. The flip-flops and the logic gates of the emission control driver include positive channel metal oxide semiconductors (PMOS) transistors.

  • Patent number: 7602172
    Abstract: A test apparatus includes one handler connected to a tester and one test board divided into two or more sites or two or more test boards. Since only the sites on the test board (or test boards) need be duplicated, rather than the loading lanes or sorters of the handler, the test apparatus can be conveniently compact. Further, while testing semiconductor devices on one site or one test board, semiconductor devices in another site or on another test board can be sorted according to the test result. This enables the reduction or elimination of tester idle time to optimize the efficiency of the test apparatus.

  • Patent number: 7598571
    Abstract: A method of manufacturing a semiconductor device which can prevent leakage current caused by gate electrodes intersecting element isolation layers in a major axis of an active region, and which further has vertical channels to provide a sufficient overlap margin, and a semiconductor device manufactured using the above method. The device includes gate electrodes formed on element isolation layers that are disposed between active regions and have top surfaces that are higher than the top surfaces of the active regions. Since the gate electrodes are formed on the element isolation layers, leakage current in a semiconductor substrate is prevented. In addition, the gate electrodes are formed using a striped shape mask pattern, thereby obtaining a sufficient overlap margin compared to a contact shape or bar shape pattern.
