  • APPARATUS FOR CONTROLLING ACTIVATION PERIOD OF WORD LINE OF VOLATILE MEMORY DEVICE AND METHOD THEREOF
    Publication number: 20070280019
    Abstract: An apparatus for controlling an activation period of a word line of a volatile memory device is disclosed. The apparatus adjusts the activation period of the word line using a member for adjusting a pulse width of a pulse signal that activates the word line according to an operation mode of the volatile memory device.
    Type: Application

  • Bit line sense amplifier control circuit
    Publication number: 20070070751
    Abstract: A bit line sense amplifier control circuit comprises a driving signal generating unit adapted and configured to generate first through third driving signals in response to a bit line sense amplifier enable signal and an overdrive enable signal for setting an overdrive period, and to disable a first driving signal which is enabled for an overdrive period in response to a refresh signal which is enabled at a refresh mode, and a bit line sense amplifier control signal generating unit adapted and configured to generate first and second bit line sense amplifier control signals in response to the first through third driving signals. As a result, an overdrive pulse is not generated at a refresh mode to remove an overdriving period, thereby reducing current consumption at a refresh mode.
