  • Patent number: 7501881
    Abstract: The boosting voltage generating circuit of example embodiments may include a boosting level detection unit, a first boosting pump, and a second boosting pump. The boosting level detection unit may be configured to generate a target level detection signal and a margin level detection signal. The target level detection signal may have a logic state according to a level of a boosting voltage compared with a target voltage level, and the margin level detection signal may have a logic state according to a level of the boosting voltage compared with a margin voltage level, the margin voltage level being higher than the target voltage level. The first boosting pump may be controlled based on a target voltage level. The second boosting pump may be controlled based on a margin voltage level. According to the boosting voltage generating circuit of example embodiments, overshoot of the boosting voltage by the second boosting pump may remarkably decrease.

  • Publication number: 20090040134
    Abstract: Provided are a terminal having dual display units and a method for inputting letters therein. The terminal has a main display unit on one side, and a sub-display unit and an input unit on other side. When a screen-flip is requested, a second input window is displayed on the sub-display unit while the main display unit is displaying a first input window. When a letter is selected through the input unit, the selected letter is displayed on the second input window. The displayed letter is saved according to a letter-save request. The saved letter is displayed on the first input window. Therefore, the usability of the main display unit is increased.
