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 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： 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.
