  • Publication number: 20240079066
    Abstract: Technology is disclosed herein for early erase termination as a counter-measure for erase disturb. Multiple erase blocks of NAND memory cells are erased in parallel during an erase procedure. Erasing multiple erase blocks in parallel can place considerable strain on the circuitry that generates the erase voltage. If there is significant leakage current in one of the erase blocks the magnitude of the erase voltage for all of the erase blocks may drop. The erase blocks are tested sequentially for leakage current during the first erase loop while the erase voltage is applied to only the erase block under test. If any erase block fails the leakage current test that erase block is removed from the erase procedure. One or more additional erase loops are then performed with only those erase blocks that passed the leakage current test simultaneously receiving an erase voltage, thereby preventing erase disturb with early termination.

  • Patent number: 9126143
    Abstract: Provided is a process for integrating treatment of off gas through NOx removal, SOx removal and mercury removal, which could avoid high energy consumption resulting from high temperature required for the reaction, and a corresponding apparatus thereof. The process comprises the splitting of the off gas to a sub-stream off gas flow line as a carrier for the oxidizing agent.

  • Publication number: 20150225660
    Abstract: A hydrocarbon fuel antioxidant comprises a compound having a following molecular structure R1-(CnHm)-R2, a precursor or a derivative of the compound: wherein n and m are positive integers; —(CnHm)— group is a straight chain molecule segment formed by covalent linkage of carbon atoms which are more than or equal to 3 and less than or equal to 50; ,R1 and R2 comprise an aromatic ring or carboxylic acid or hydroxyl radical or alkyl group; the aromatic ring group may either be a single ring or polycyclic, and may also be a heterocycle containing oxygen or nitrogen, which may be provided with or not provided with a substituent group; the antioxidant contains more than one linear chain or ring conjugated bond formed by conjugated double bonds; the ring conjugated double bonds are located on the aromatic ring at the end part; the linear chain conjugated double bonds are located on a carbon chain in the middle; and the antioxidant has a prominent absorption peak in a 250-400 nm ultraviolet wavelength range.

  • Publication number: 20130192979
    Abstract: An apparatus for plasmatizing solid-fuel combustion additive and the method for using the same are provided. The apparatus is made from a reaction vessel, electrodes, a power supply, a carrier gas intake device, a feed device and an outlet of the plasmatization reaction vessel. The method to use this apparatus is as following: The additive is added into the reaction vessel through the feed device in which the carrier gas passes and carries the additive into the electrode region for evaporation and (partially) plasmatization; and the plasmatized gas from the outlet of the reactor is introduced into any combustion chamber. The additive is an organometallic compound or a mixture of the organometallic compounds, or their derivative, eutectic compound or coordination agent containing at least one organometallic compound.
