摘要:
A semiconductor memory device and a layout structure of sub-word line control signal generators. The sub-word line control signal generators are configured to supply a sub-word line control signal of a predefined voltage level to a sub-word line driver to enable a sub-word line of a memory cell array. At least two sub-word line control signal generators are disposed, respectively, at edge areas of the memory cell array, to directly supply the sub-word line control signal to one selected sub-word line driver, thereby reducing the power consumption, including for example, VPP voltage. Embodiments of the present invention also reduce the number of VPP power lines, thereby lessening a noise disturbance.

摘要:
An electron emission display includes: a rear plate including an electron emission device; a front plate spaced from the rear plate and including a fluorescent layer adapted to emit light in response to electrons emitted by the electron emission device colliding with the fluorescent layer; and a grid electrode arranged in a space between the rear and front plates and having a grid substrate including an aperture through which electrons emitted by the electron emission device pass and a film of a photo absorbing material arranged on a surface of the grid substrate. With this configuration, light from a fluorescent layer or secondary electrons, which travel towards a rear plate while the electron emission display operates, are absorbed in the blackened film to prevent other fluorescent layers from emitting light, thereby improving brightness and color purity of the electron emission display.

A nonvolatile memory device includes a memory cell array including a plurality of cell strings each having a plurality of memory cells stacked in a direction perpendicular to a substrate, and a peripheral circuit region including a plurality of transistors electrically connected to the memory cell array through a plurality of conductive lines. Each of the transistors includes a gate electrode crossing an active region of the substrate in a first direction and source and drain regions in the active region at the opposite sides of the gate electrode. In at least one of the transistors, the number of source contact plugs connected to the source region is different from the number of drain contact plugs connected to the drain region.
