  • Patent number: 8159860
    Abstract: A data path circuit includes a bit line sense amplifier, a local input/output line precharger connected to a local input/output line pair, a global input/output line precharger connected to a global input/output line pair, a column selector connecting a bit line pair connected to the bit line sense amplifier and the local input/output line pair to each other in response to a column selection signal, and a local input/output line selector connecting the local input/output line pair and the global input/output line pair to each other in response to a multiplexing control signal. A discharge path generator decreases the potential on the global input/output line pair down to a predetermined level in response to a data masking control signal which is activated earlier than the column selection signal during a data masking operation mode.

  • Patent number: 7878189
    Abstract: A combustion fan installation structure of a gas radiation oven range is disclosed in which a combustion fan (200) is coupled at a space outside a space where a radiant burner (40) is positioned. Since the temperature of the sucked air for combustion is constantly maintained, an air with a sufficient air density can be supplied. Thus, it can have a stable combustion performance. In addition, an influence of the temperature change generated when the oven or the grill is operated can be excluded. Accordingly, a reliability of a combustion performance of the gas radiation oven range to be mainly used in kitchens or in hotels can be improved.

  • Patent number: 7786752
    Abstract: According to one aspect, an on-die termination (ODT) circuit is controlled during transition from a first power mode to a second power mode of a memory device. The transition from an asynchronous ODT circuit path to a synchronous ODT circuit path is delayed to compensate for an operational latency of a delay locked loop (DLL) circuit.

  • Patent number: 7274584
    Abstract: Provided are a semiconductor memory device having a wordline enable signal line arrangement scheme, which can reduce VPP power consumption and can increase the speed of driving a sub-wordline, and a method of arranging wordline enable signal lines in the semiconductor memory device. In the semiconductor memory device, a wordline enable driver is arranged in a row decoder region outside a memory array region, and the wordline enable signal lines are formed of an uppermost metal layer among three metal layers constituting the semiconductor memory device. Each of the wordline enable signal lines is connected to a sub-wordline driver, rather than to a pair of sub-wordline drivers. In other words, the wordline enable signal lines vertically and horizontally extend forming an inverse L shape.
