  • Publication number: 20070076493
    Abstract: A circuit for generating a data strobe signal of a semiconductor memory device comprises a plurality of internal clock delay units, a selecting control unit and a pulse generating unit. The plurality of internal clock delay units delay an internal clock signal in response to a plurality of CAS latency signal. The selecting control unit logically combines a data latch control signal to latch input data with output signals from the plurality of internal clock delay units. The pulse generating unit generates the data strobe signal having a predetermined pulse in response to an output signal from the selecting control unit. In the circuit, a tDQSS margin is regulated depending on change of tCK of an operating frequency in response to a CAS latency signal.

  • Publication number: 20060134856
    Abstract: A method for manufacturing a capacitor of a semiconductor element including: forming a bottom electrode of the capacitor on a semiconductor substrate; performing rapid thermal nitrification (RTN) on the upper surface of the bottom electrode; performing a thermal process on the obtained structure having the bottom electrode in a furnace under a nitride atmosphere to eliminate stress generated by the RTN; forming Al2O3 and HfO2 dielectric films on the nitrified bottom electrode; and forming a plate electrode of the capacitor on the Al2O3 and HfO2 dielectric films. The thermal process is performed after the RTN performed on the surface of the bottom electrode, so that stress, generated from the RTN, is alleviated, thereby allowing the capacitor to obtain a high capacitance and lowering leakage current.

  • Publication number: 20060104119
    Abstract: A local input/output line precharge circuit of a semiconductor memory device comprises a precharge control unit, an equalization unit and a data output unit. The precharge control unit outputs a precharge control signal to precharge a pair of local input/output lines in response to a continuous write signal activated when a write operation continues. The equalization unit precharges and equalizing the pair of local input/output lines in response to the precharge control signal. The data output unit outputs data signals of a pair of global input/output lines to the pair of local input/output lines in response to output signal from the equalization unit. In the circuit, a local input/output line precharge operation is not performed at a continuous write mode, thereby reducing current consumption.
