  • Publication number: 20240124292
    Abstract: An auxiliary operation device for a droplet dispenser includes a droplet sensor, an imaging device and a processor. The droplet sensor has a detected area located between a droplet dispenser and a target area, wherein the droplet sensor detects a droplet output from the droplet dispenser, and outputs a corresponding droplet detection signal. The imaging device captures an image of the target area. The processor obtains a dripping time point at which the droplet passes through the detected area according to the droplet detection signal, and determines whether the target area is shielded within a first time range according to the image, so as to evaluate whether the droplet has successfully dropped into the target area. The above-mentioned auxiliary operating device of the droplet dispenser can objectively determine whether the droplets successfully drops into the target area, and improve the accuracy of judgment.

  • Patent number: 8723559
    Abstract: A circuit usable as a word line driver includes a driver that switches in response to a voltage on a control node, and a circuit supplying a voltage to the control node. The circuit that applies a voltage to control node provides a first static current tending to pull the control node up to a first source voltage, and provides a fighting current pulse in response to a signal selecting the driver to pull the control node down to a second source voltage, overcoming the first static current. In addition, a circuit provides a pull-up boost current on a transition of the signal selecting the driver that turns off the fighting current, and applies a boosting current pulse to the control node to assist pulling the control node quickly to the first source voltage.

  • Patent number: 7692960
    Abstract: A method for improving an over erasing effect of a charge-trapping memory cell. The charge-trapping memory cell has a transistor, which has a first terminal coupled to a first bit line and a second terminal coupled to a second bit line. First, the method erases the charge-trapping memory cell. Then, after the charge-trapping memory cell is completely erased, the first bit line is electrically connected to the second bit line to make a voltage level of the first bit line equal a voltage level of the second bit line such that the voltage level of the first terminal of the transistor equals the voltage level of the second terminal of the transistor.

  • Publication number: 20080159060
    Abstract: A method for accessing a memory sequentially. The memory has (m+1) bit lines and at least one row of transistors, wherein m is a positive integer. This method includes the following steps. First, voltage levels of first and second terminals of the transistors are equalized to a ground voltage in a pre-discharge period. Next, the voltage levels of the first and second terminals of the nth transistor are respectively transformed into a source voltage and a drain voltage in an nth reading period, and the voltage level of the second terminal of the (n+1)th transistor is transformed into an isolation voltage, wherein n is a positive integer smaller than m. Thereafter, the voltage levels of the first and second terminals of the mth transistor are respectively transformed into the source voltage and the drain voltage in an mth reading period. The source voltage equals the ground voltage.
