Abstract: A touch controller is coupled to a touch screen and detects a first gesture at a first point on the touch screen. The first gesture includes physical contact of the touch screen by a user device at the first point. The touch controller detects a second gesture that is associated with movement of the user device from the first point to a second point on the touch screen. The second gesture includes detecting movement of the user device within a sensing range from the first point to the second point. The sensing range corresponds to an orthogonal distance from a surface of the touch screen. The touch controller detects a third gesture at the second touch point. The third gesture includes physical contact of the touch screen at the second touch point. Upon detecting the first, second and third gestures the touch controller performs a corresponding action.

Abstract: A non-volatile memory device with a page buffer having dual registers includes a memory cell array, a selector circuit and a page buffer circuit, the selector circuit being coupled to an exterior data line, the page buffer circuit including a first register and a second register being coupled between the memory cell array and the selector circuit, and the first register and second register being commonly coupled through a sense node. The first and second registers alternately write data to the memory cell array for programming. As one of the first and second registers performs programming, the other register stores data from the data line concurrently. In other words, the second register stores data from the data line when the first register is in programming, whereas the first register stores data from the data line when the second register is in programming.
