  • Publication number: 20110122685
    Abstract: A multi-level cell (MLC) phase-change memory device divides data into data groups each comprising multiple bits of data, and stores each of the data groups in a selected phase-change memory cell. A data group is stored in a selected phase-change memory cell by applying a pulse current to the selected phase-change memory cell with a pulse current characteristic corresponding to a data value of the data group. The pulse current characteristic can comprise, for instance, a magnitude, downward slope, or duration of the pulse current. Data is read from a selected phase-change memory cell by sensing a voltage of a bitline connected to the selected phase-change memory cell and comparing the sensed voltage simultaneously with a plurality of reference voltages.

    Abstract: In a semiconductor device and a method of manufacturing the same, a first insulation layer is removed from a cell area of a substrate and a first active pattern is formed on the first area by a laser-induced epitaxial growth (LEG) process. Residuals of the first insulation layer are passively formed into a first device isolation pattern on the first area. The first insulation layer is removed from the second area of the substrate and a semiconductor layer is formed on the second area of the substrate by a SEG process. The semiconductor layer on the second area is patterned into a second active pattern including a recessed portion and a second insulation pattern in the recessed portion is formed into a second device isolation pattern on the second area.

  • Publication number: 20110012521
    Abstract: In a display apparatus having a backlight unit, a light unit includes plural light source strings commonly connected to an output terminal of a boosting circuit to generate light in response to a light source driving voltage. The light source strings are grouped into plural light generating groups. Plural driving circuits are respectively connected to the light generating groups, and each driving circuit sequentially outputs feedback voltages from the light source strings of a corresponding light generating group. A minimum voltage detecting circuit compares the feedback voltages with each other from the driving circuits to detect a minimum voltage and outputs a control signal according to the detected minimum voltage. A voltage control circuit controls a voltage level of the light source driving voltage in response to the control signal. Accordingly, although the number of the driving circuits increases, power consumption used in each driving circuit may be reduced.
