  • Patent number: 9595315
    Abstract: A semiconductor memory device includes a bit line sense amplifier, a first column select gate, and a second column select gate. The bit line sense amplifier senses an electric potential difference between a bit line and a complementary bit line during a sensing operation for memory cells. The first column select gate transfers an electric potential on the bit line to a local sense amplifier based on a column select signal. The second column select gate transfers an electric potential on the complementary bit line to the local sense amplifier based on the column select signal. The first and second column select gates have different current drive abilities to compensate a difference in bit line interconnection resistance.

  • Patent number: 7111247
    Abstract: The present invention relates to a device and method for displaying various menus of a microwave oven onto one screen. In the present invention, the various menus can be displayed onto one screen by using a tree structure or window structure. To this end, display control data are stored such that the various menus can be displayed in the form of the tree structure or display window. These display control data are stored in a separately provided storage device. According to the present invention constructed as such, since the user can confirm the various functions of the microwave oven on the same screen at one time, there is an advantage in that trials and errors made when using the microwave oven can be minimized. In addition, since all the functions can be confirmed simultaneously, there are further advantages in that the time required for learning how to use the microwave oven is reduced and function selection can be conveniently made.

  • Patent number: 6133559
    Abstract: A first highest temperature of a load is detected during a current cycle. A second highest temperature of the load is detected during a last cycle. An actual temperature of the load is estimated in real time based on a gradient between the first and second highest temperatures. The estimated actual temperature and an actual temperature of the load detected by a sensor are compared to each other in real time, and the higher temperature is set as a current temperature. A heating operation is continued until the current temperature reaches a preset temperature.
