  • Patent number: 9934853
    Abstract: The present disclosure relates to a method and apparatus for performing a read operation of an RRAM cell, which applies a non-zero bias voltage to unselected bit-lines and select-lines to increase a read current window without damaging corresponding access transistors. In some embodiments, the method may be performed by activating a word-line coupled to a row of RRAM cells comprising a selected RRAM device by applying a first read voltage to the word-line. A second read voltage is applied to a bit-line coupled to a first electrode of the selected RRAM device. One or more non-zero bias voltages are applied to bit-lines and select-lines coupled to RRAM cells, within the row of RRAM cells, having unselected RRAM devices.

  • Publication number: 20180032093
    Abstract: A water valve includes a valve body, a stationary sleeve, and a movable sleeve. The stationary sleeve is received in the valve body, and the movable sleeve is slidably disposed in the stationary sleeve. A partition plate is formed in the movable sleeve to partition the movable sleeve into a cold water cavity and a hot water cavity at two ends respectively. An external wall of the movable sleeve is formed with an annular groove positionally corresponding to the partition plate. When the partition plate is pushed under different pressure of cold water and hot water, the movable sleeve is moved to regulate flow ratio of cold water and hot water. Besides, water is received in the annular groove and the gap between the stationary sleeve and the movable sleeve for cushion and lubrication. Thus, the movable sleeve is easier to move for regulation.
