    • 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.
    • 本文公开了动态地确定芯片上的读取电平(例如,存储器管芯)。 一种方法包括以第一组读取级别在存储器管芯上读取一组非易失性存储元件。 两个最新的读取电平的结果存储在存储器管芯上。 确定组中有多少非易失性存储元件在两个最新读取级别的读取之间显示不同的结果。 使用存储在存储器管芯上的结果在存储器管芯上进行确定。 当计数达到预定标准时,基于读取级别来确定动态读取级别以区分多个数据状态的第一对相邻数据状态。 注意,读取电平可以在存储器管芯上动态地确定。
