摘要： A set of non-volatile storage elements are subjected to a programming process in order to store data. During the programming process, one or more verification operations are performed to determine whether the non-volatile storage elements have reached their target. Non-volatile storage elements being programmed to a first set of one or more targets are verified to determine whether they have reached their target and are locked out of further programming if it is determined that they have reached their target. Non-volatile storage elements being programmed to the second set of one or more targets are tested to determine the number of fast programming bits. When the number of fast bits for a particular target is greater than a threshold, then programming stops for the non-volatile storage elements being programmed to the particular target.

摘要： A hybrid method of programming a non-volatile memory cell to a final programmed state is described. The method described is a more robust protocol suitable for reliably programming selected memory cells while eliminating programming disturbs. The hybrid method comprises programming the non-volatile memory cell to a first state according to a first coarse programming mechanism, and programming the non-volatile memory cell according to a second different more precise programming mechanism thereby completing the programming of the non-volatile memory cell to the final programmed state. Additionally, the described method is particularly advantageous for programming multilevel chips.

摘要： Dynamically determining read levels on chip (e.g., memory die) is disclosed herein. One method comprises reading a group of non-volatile storage elements on a memory die at a first set of read levels. Results of the two most recent of the read levels are stored on the memory die. A count of how many of the non-volatile storage elements in the group showed a different result between the reads for the two most recent read levels is determined. The determining is performed on the memory die using the results stored on the memory die. A dynamic read level is determined for distinguishing between a first pair of adjacent data states of the plurality of data states based on the read level when the count reaches a pre-determined criterion. Note that the read level may be dynamically determined on the memory die.

摘要： A system is disclosed for programming non-volatile storage that improves performance by setting the starting programming voltage to a first level for fresh parts and adjusting the starting programming voltage as the memory is cycled. For example, the system programs a set of non-volatile storage elements during a first period using an increasing program signal with a first initial value and subsequently programs the set of non-volatile storage elements during a second period using an increasing program signal with a second initial value, where the second period is subsequent to the first period and the second initial value is different than the first initial value.

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.
