    摘要： A semiconductor memory device may include active regions defined on a substrate by a device isolation layer, each of the active regions including a first impurity region and a second impurity region, word lines on the active regions and extended in a first direction, capping insulating patterns covering top surfaces of the word lines, respectively, bit lines on the word lines and extended in a second direction crossing the first direction, contact plugs between the bit lines and connected to the second impurity region, and data storages on the contact plugs, respectively. Each of the word lines may include a first metal nitride layer and a second metal nitride layer on the first metal nitride layer. A resistivity of the second metal nitride layer may be smaller than a resistivity of the first metal nitride layer.

    摘要： A display device includes: a charge sharing controller to generate the plurality of group switch control signals based on first bits of (K−1)th digital data groups and second bits of digital data groups. The (K−1)th digital data groups correspond to pixel values of a (K−1)th row of the display panel. The Kth data digital groups correspond to pixel values of a Kth row of the display panel. The charge sharing controller is configured to, with respect to each of the plurality of source line groups, activate each of the plurality of group switch control signals to perform the charge sharing in response to the first bits satisfying a first condition, and the first bits and the second bits satisfying a second condition. The first bits and the second bits are not compared to each other to output a count value.

    摘要： A display driver integrated circuit includes a gamma circuit, a control circuit, and an output buffer circuit. The gamma circuit generates a plurality of gamma voltages based on gamma control information, a first gamma power supply voltage and a second gamma power supply voltage. The control circuit calculates a gamma limit value based on panel brightness information, voltage levels of the first and second gamma power supply voltages and the number of the plurality of gamma voltages. The control circuit generates a mode determination signal. The output buffer circuit includes a plurality of buffer circuits. Each of the plurality of buffer circuits includes an input stage and the input stage includes first transistors and second transistors. In a first driving mode, each of the plurality of buffer circuits turns off the first transistors and turns on the second transistors included in the input stage.
