摘要： Shifts in the apparent charge stored on a floating gate (or other charge storing element) of a non-volatile memory cell can occur because of the coupling of an electric field based on the charge stored in adjacent floating gates (or other adjacent charge storing elements). To compensate for this coupling, the read or programming process for a given memory cell can take into account the programmed state of an adjacent memory cell. To determine whether compensation is needed, a process can be performed that includes sensing information about the programmed state of an adjacent memory cell (e.g., on an adjacent bit line or other location).

摘要： Techniques of reducing erroneous readings of the apparent charge levels stored in a number of rows of memory cells on account of capacitive coupling between the cells. All pages of a first row are programmed with a first pass, followed by programming all pages of a second adjacent row with a first pass, after which the first row is programmed with a second pass, and then all pages of a third row are programmed with a first pass, followed by returning to program the second row with a second pass, and so on, in a back-and-forth manner across the rows of an array. This minimizes the effect on the apparent charge stored on rows of memory cells that can occur by later writing data into adjacent rows of memory cells.

摘要： In a non-volatile memory programming scheme where the memory cells are programmed in two or more sequential programming passes, when there is insufficient host data to program at least some of the memory cells during the second pass, some of the memory cells may be programmed to the wrong threshold voltage. This can be prevented by modifying the programming scheme so that this does not occur. In one implementation, this is accomplished by choosing a code scheme, which does not cause the memory cells to be programmed to the wrong threshold voltage during the second programming pass, or by programming the memory cells in accordance with substitute data that would not cause the cells to be programmed to an erroneous state.

摘要： To program a set of non-volatile storage elements, a set of programming pulses are applied to the control gates (or other terminals) of the non-volatile storage elements. The programming pulses have a constant pulse width and increasing magnitudes until a maximum voltage is reached. At that point, the magnitude of the programming pulses stops increasing and the programming pulses are applied in a manner to provide varying time duration of the programming signal between verification operations. In one embodiment, for example, after the pulses reach the maximum magnitude the pulse widths are increased. In another embodiment, after the pulses reach the maximum magnitude multiple program pulses are applied between verification operations.

摘要： A system is disclosed for reducing or removing a form of read disturb in a non-volatile storage device. One embodiment seeks to prevent read disturb by eliminating or minimizing boosting of the channel of the memory elements. For example, one implementation prevents or reduces boosting of the source side of the NAND string channel during a read process. Because the source side of the NAND string channel is not boosted, at least one form of read disturb is minimized or does not occur.
