  • SEMICONDUCTOR MEMORY DEVICE AND LAYOUT STRUCTURE OF SUB-WORD LINE CONTROL SIGNAL GENERATOR
    Publication number: 20110075505
    Abstract: 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.
