  • Patent number: 8203904
    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.

  • Patent number: 8125249
    Abstract: A frequency measuring circuit and a semiconductor device having the frequency measuring circuit include a divided and shifted clock signal generator, a delayed clock signal generator and a phase detecting unit. The divided and shifted clock signal generator divides a frequency of a clock signal input from an exterior to output a frequency-divided clock signal, and delays the frequency-divided clock signal by a time proportional to a period of the clock signal to output a shifted clock signal. The delayed clock signal generator delays the frequency-divided clock signal by a fixed time to generate a plurality of delayed clock signals. The phase detecting unit receives the plurality of delayed clock signals and the shifted clock signal and detects a phase difference between each of the plurality of delayed clock signals and the shifted clock signal to output a plurality of phase detecting signals that represent information related to a frequency of the clock signal.
