    • Memory die are provided with programmable chip enable circuitry to allow particular memory die to be disabled after packaging and/or programmable chip address circuitry to allow particular memory die to be readdressed after being packaged. In a multi-chip memory package, a memory die that fails package-level testing can be disabled and isolated from the memory package by a programmable circuit that overrides the master chip enable signal received from the controller or host device. To provide a continuous address range, one or more of the non-defective memory die can be re-addressed using another programmable circuit that replaces the unique chip address provided by the pad bonding. Memory chips can also be also be readdressed after packaging independently of detecting a failed memory die.

    • Systems and methods in accordance with various embodiments can provide for comprehensive erase verification and defect detection in non-volatile semiconductor memory. In one embodiment, the results of erasing a group of storage elements is verified using a plurality of test conditions to better detect defective and/or insufficiently erased storage elements of the group. For example, the results of erasing a NAND string can be verified by testing charging of the string in a plurality of directions with the storage elements biased to turn on if in an erased state. If a string of storage elements passes a first test process or operation but fails a second test process or operation, the string can be determined to have failed the erase process and possibly be defective. By testing charging or conduction of the string in a plurality of directions, defects in any transistors of the string that are masked under one set of conditions may be exposed under a second set of bias conditions. For example, a string may pass an erase verification operation but then be read as including one or more programmed storage elements. Such a string can be defective and mapped out of the memory device.
    • 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的全面擦除验证和缺陷检测。 在一个实施例中,使用多个测试条件来验证擦除一组存储元件的结果,以更好地检测组中的有缺陷和/或不充分擦除的存储元件。 例如,擦除NAND串的结果可以通过在多个方向上测试字符串的充电来验证,其中存储元件被偏置为在擦除状态下导通。 如果一串存储元件通过第一个测试过程或操作,但是失败了第二个测试过程或操作,则可以确定该字符串已经失效了擦除过程并且可能是有缺陷的。 通过在多个方向上测试串的充电或导通,在一组条件下被屏蔽的串的任何晶体管中的缺陷可能在第二组偏置条件下暴露。 例如,字符串可以传递擦除验证操作,然后被读取为包括一个或多个编程的存储元件。 这样的字符串可能是有缺陷的,并被映射出存储器件。

    • A new, non-wrapping approach to solubilize nanotubes, such as carbon nanotubes, in organic and inorganic solvents is provided. In accordance with certain embodiments, carbon nanotube surfaces are functionalized in a non-wrapping fashion by functional conjugated polymers that include functional groups for solubilizing such nanotubes. Various embodiments provide polymers that noncovalently bond with carbon nanotubes in a non-wrapping fashion. For example, various embodiments of polymers are provided that comprise a relatively rigid backbone that is suitable for noncovalently bonding with a carbon nanotube substantially along the nanotube's length, as opposed to about its diameter. In preferred polymers, the major interaction between the polymer backbone and the nanotube surface is parallel π-stacking. The polymers further comprise at least one functional extension from the backbone that are any of various desired functional groups that are suitable for solubilizing a carbon nanotube.

    • In a flash EEPROM system that is divided into separately erasable blocks of memory cells with multiple pages of user data being stored in each block, a count of the number of erase cycles that each block has endured is stored in one location within the block, such as in spare cells of only one page or distributed among header regions of multiple pages. The page or pages containing the block cycle count are initially read from each block that is being erased, the cycle count temporarily stored, the block erased and an updated cycle count is then written back into the block location. User data is then programmed into individual pages of the block as necessary. The user data is preferably stored in more than two states per memory cell storage element, in which case the cycle count can be stored in binary in a manner to speed up the erase process and reduce disturbing effects on the erased state that writing the updated cycle count can cause. An error correction code calculated from the cycle count may be stored with it, thereby allowing validation of the stored cycle count.
    • 在被分成具有存储在每个块中的多页用户数据的存储单元的单独可擦除块的快闪EEPROM系统中,每个块已经承受的擦除周期数的计数被存储在块内的一个位置中, 如在仅一页的备用单元中或分布在多页的标题区之间。 最初从被擦除的每个块读取包含块循环计数的页面,临时存储循环计数,擦除块,然后将更新的循环计数写回到块位置。 然后根据需要将用户数据编程到块的各个页面中。 用户数据优选地存储在每个存储器单元存储元件的多于两个状态中,在这种情况下,周期计数可以以加速擦除处理的方式以二进制存储,并且减少写入更新周期的擦除状态的干扰效应 计数可以造成。 可以与循环计数一起存储从周期计数中计算的纠错码,从而允许验证存储的循环计数。
