Abstract: Methods and systems are provided for fabricating a large format lithium ion electrochemical cell that includes an anode and a cathode. In one example, the anode is prepared via loading the anode to a predetermined anode loading amount, followed by electrochemical pre-lithiation of the anode via electrically coupling an auxiliary electrode to the anode where lithium is transferred to the anode through an electrolyte solution from the auxiliary electrode. In this way, pre-lithiation of the anode may be improved, which may in turn increase a capacity of the large format lithium ion electrochemical cell.

Abstract: Techniques are described for reducing an injection type of program disturb in a memory device during the pre-charge phase of a program loop. In one approach, a pre-charge voltage on the selected word line and drain side word lines is adjusted based on a risk of the injection type of program disturb. Risk factors such as temperature, WLn position, Vpgm and the selected sub-block, can be used to set the pre-charge voltage to be lower when the risk is higher. In another approach, the pre-charge voltage on the source side word lines is adjusted to reduce a channel gradient and/or the amount of time in which the injection type of program disturb occurs.

Abstract: Techniques are described for maintaining a pre-charge voltage in a NAND string in a program operation. After a pre-charge voltage is applied to the channel of a NAND string, the word line voltages are controlled to avoid a large channel gradient which generates electron-hole pairs, where the electrons can pull down the channel boosting level on the drain side of the selected word line. In one approach, the word line voltages of a group of one or more source side word lines adjacent to the selected word line are increased directly from the level used during pre-charge to a pass voltage. The word line voltages of other source side word lines, and of drain side word lines, can be decreased and then increased to the pass voltage to provide a large voltage swing which couples up the channel.

Abstract: Techniques for reducing neighbor word line interference (NWI) of memory cells which are formed in a two-tier stack having a lower tier and an upper tier separated by an interface. In one approach, an upward word line programming order is used for a top portion of the top tier, and a downward word line programming order is used for a bottom portion of the top tier and for the bottom tier. Additionally, for memory cells which receive NWI from both adjacent word lines, options include programming fewer bits per cell, performing multi-pass programming and/or use lower verify voltages. Options also include increasing a control gate length of the memory cells and increasing a height of a dielectric region adjacent to the memory cells.

Abstract: A gene of interest and the gene encoding hypoxanthine-aminopterin-thymidine (HPRT) can be co-targeted for Casp9 nuclease-mediated editing or alteration in a cell. Based on whether the HPRT gene is altered to encode a non-functional protein, or is not so-altered, the co-targeted cells can be selected and counter-selected. HPRT co-targeting can be used to sequentially disrupt as many genes of interest as cell viability permits.

Abstract: Techniques for reducing read disturb of memory cells in a two-tier stack having a lower tier and an upper tier separated by an interface. In a read operation, the channels of NAND strings are discharged before reading the selected memory cells. A discharge period is set based on a position of the selected word line in a stack or block of memory cells. The discharge period is longer when the selected word line is in the lower tier than in the upper tier. Additionally, the discharge period is longer when the selected word line is at a top of the lower tier than at a bottom of the lower tier. Other options to increase the discharge include increasing a ramp up rate and a peak level of the word line voltages during the discharge period as a function of the position of the selected word line.

Abstract: Techniques are disclosed for reducing an injection type of program disturb in a memory device. In one aspect, a discharge operation is performed at the start of a program loop. This operation discharges residue electrons from the channel region on the source side of the selected word line, WLn, to the channel region on the drain side of WLn. As a result, in a subsequent channel pre-charge operation, the residue electrons can be more easily removed from the channel. The discharge operation involves applying a voltage pulse to WLn and a first set of drain-side word lines which is adjacent to WLn. The remaining unselected word lines may be held at ground during the voltage pulse.
