    • 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 neighboring floating gates (or other neighboring charge storing elements). The problem occurs most pronouncedly between sets of adjacent memory cells that have been programmed at different times. To compensate for this coupling, the read process for a given memory cell will take into account the programmed state of a neighbor memory cell if the neighbor memory cell was programmed subsequent to the given memory cell. Techniques for determining whether the neighbor memory cell was programmed before or after the given memory cell are disclosed.
    • 存在于非易失性存储单元的浮动栅极(或其他电荷存储元件)上的表观电荷的变化可能发生,因为基于存储在相邻浮动栅极(或其他相邻电荷存储元件)中的电荷的电场的耦合 )。 在不同时间编程的相邻存储器单元组之间最明显地出现该问题。 为了补偿该耦合,如果相邻存储器单元在给定存储器单元之后被编程,则给定存储器单元的读取过程将考虑相邻存储器单元的编程状态。 公开了用于确定相邻存储器单元是否在给定存储器单元之前或之后被编程的技术。

    • Systems and methods in accordance with various embodiments can provide for reduced program disturb in non-volatile semiconductor memory. In one embodiment, select memory cells such as those connected to a last word line of a NAND string are programmed using one or more program verify levels or voltages that are different than a corresponding level used to program other cells or word lines. One exemplary embodiment includes using a lower threshold voltage verify level for select physical states when programming the last word line to be programmed for a string during a program operation. Another embodiment includes applying a lower program voltage to program memory cells of the last word line to select physical states. Additional read levels are established for reading the states programmed using lower verify levels in some exemplary implementations. A second program voltage step size that is larger than a nominal step size is used in one embodiment when programming select memory cells or word lines, such as the last word line to be programmed for a NAND string.
    • 根据各种实施例的系统和方法可以提供非易失性半导体存储器中减少的程序干扰。 在一个实施例中,使用与编程其他单元或字线的相应级别不同的一个或多个程序验证电平或电压对连接到NAND串的最后字线的选择存储器单元进行编程。 一个示例性实施例包括在编程在程序操作期间编程用于字符串的最后一个字线时,使用较低的阈值电压验证电平来选择物理状态。 另一个实施例包括将较低编程电压施加到最后字线的编程存储单元以选择物理状态。 在一些示例性实施方式中,建立读取使用较低验证电平编程的状态的附加读取电平。 在一个实施例中,当编程选择存储器单元或字线(诸如要为NAND串编程的最后字线)时,使用大于标称步长的第二编程电压步长。
