    • Shifts in the apparent charge stored on a 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 charge storing elements. To compensate for this coupling, the programming process for a given memory cell can take into account the target programmed state of one or more adjacent memory cell. The amount of programming is verified after each programming pulse and the standard verify level for the programming cell is dependent on the target state. The verify level is further offset lower dependent on the amount of perturbation from neighboring cells, determinable by their target states. The verify level is preferably virtually offset by biasing adjacent word lines instead of actually offsetting the standard verify level. For soft-programming erased cells, neighboring cells on both adjacent word lines are taken into account.
    • 由于存储在相邻的电荷存储元件中的电荷的电场的耦合,可能会发生存储在非易失性存储单元的电荷存储元件上的视在电荷的变化。 为了补偿该耦合,给定存储器单元的编程过程可以考虑一个或多个相邻存储器单元的目标编程状态。 在每个编程脉冲之后验证编程量,编程单元的标准验证电平取决于目标状态。 验证级别进一步偏移较低,取决于相邻小区的扰动量,可由其目标状态确定。 验证级别优选地通过偏置相邻字线而不是实际上抵消标准验证电平而被虚拟地偏移。 对于软编程擦除的单元,考虑两个相邻字线上的相邻单元。

    • A control method, system and function entity for reporting a bearer event of a signaling IP flow are provided. Flow identifier information such as a 5-tuple is generated for a signaling IP flow and a media IP flow so as to unify a mechanism for reporting a signaling path status and a mechanism for reporting a bearer event of a media IP flow, so that the mechanism for reporting a signaling path status is not limited by the parameter of Flow Usage, the PDP context with a signaling tag, thereby establishing corresponding PCC rules for signaling and the association between a signaling IP flow and a bearer. A method for reporting a signaling path status is further provided in the invention. In the method, for a default PDP context or a PDP context of a signaling IP flow, the predefined PCC rules are activated or signaling PCC rules generated in accordance with an Application Function address are installed, thereby an IP signaling path status is reported in accordance with rule names of the predefine PCC rules or the signaling PCC rules.

    • During programming of storage elements, channel-to-floating gate coupling effects are compensated to avoid increased programming speed and threshold voltage distribution widening. In connection with a programming iteration, unselected bit lines voltages are stepped up to induce coupling to selected bit lines, and the amount of coupling which is experienced by the selected bit lines is sensed. When a program pulse is applied, voltages of the selected bit lines are set based on the amount of coupling. The bit line voltage is set higher when more coupling is sensed. The amount of coupling experience by a given selected bit line is a function of its proximity to unselected bit lines. One or more coupling thresholds can be used to indicate that a given selected bit line has one or two adjacent unselected bit lines, respectively.
    • 在存储元件的编程期间,补偿了沟道到浮置栅极耦合效应,以避免增加的编程速度和阈值电压分布加宽。 结合编程迭代,非选择的位线电压被升高以感应到选定位线的耦合,并且感测所选位线所经历的耦合量。 当施加编程脉冲时,基于耦合量设置所选位线的电压。 当检测到更多的耦合时,位线电压被设置得更高。 给定选定位线的耦合体验量是其与未选定位线的接近度的函数。 可以使用一个或多个耦合阈值来指示给定的所选位线分别具有一个或两个相邻的未选位线。

    • During programming of storage elements, channel-to-floating gate coupling effects are compensated to avoid increased programming speed and threshold voltage distribution widening. Programming speed can be adjusted by grounding the bit line of a selected storage element until it reaches a verify level which is below a target verify level of its target data state, after which the bit line is floated so that programming speed is slowed. The verify level which triggers the floating can be a target verify level of a data state that is one or more states below the target data state. Or, the verify level which triggers the floating can be an offset verify level of the target data state. An option is to raise the bit line voltage before it floats, to enter a slow programming mode, in which case there is a double slow down.
    • 在存储元件的编程期间,补偿了沟道到浮置栅极耦合效应,以避免增加的编程速度和阈值电压分布加宽。 编程速度可以通过将选定的存储元件的位线接地直到其达到低于其目标数据状态的目标验证电平的验证电平来调整,此后位线被浮置,使得编程速度变慢。 触发浮动的验证级别可以是低于目标数据状态的一个或多个状态的数据状态的目标验证级别。 或者,触发浮动的验证级别可以是目标数据状态的偏移验证级别。 一个选项是在浮点运算之前提高位线电压,进入缓慢的编程模式,在这种情况下会出现双倍的减速。

    • A group of non-volatile memory cells are programmed in a programming pass by a series of incremental programming pulses where each pulse is followed by a program-verify and possibly program-inhibition step. Performance is improved during the programming pass by delayed starting and prematurely terminating the various verify levels that demarcate the multiple memory states. This amounts to skipping the verifying and inhibiting steps of the fastest and slowest programming (fringe) cells of the group. A reference pulse is established when the fastest cells have all been program-verified relative to a first verify level. The starting of what verify level at what pulse will then be delayed relative to the reference pulse. Verifying stops for a given verify level when only a predetermined number of cells remain unverified relative to that given level. Any errors arising from over- or under-programming of the fringe cells are corrected by an error correction code.

    • Column based defect management techniques are presented. Each column of the memory has an associated isolation latch or register whose value indicates whether the column is defective, but in addition to this information, for columns marked as defective, additional information is used to indicate whether the column as a whole is to be treated as defective, or whether just individual bits of the column are defective. The defective elements can then be re-mapped to a redundant element at either the appropriate bit or column level based on the data. When a column is bad, but only on the bit level, the good bits can still be used for data, although this may be done at a penalty of under programming for some bits, as is described further below. A self contained Built In Self Test (BIST) flow constructed to collect the bit information through a set of column tests is also described. Based on this information, the bad bits can be extracted and re-grouped into bytes by the controller or on the memory to more efficiently use the column redundancy area.
