    摘要: A method includes changing a read reference level for reading a group of memory cells as a function of changes in a threshold voltage distribution of a different group of memory cells. The changing step includes determining a history read reference level of a group of history cells associated with a group of memory cells of a non-volatile memory cell array, allowing correct reading of the group of history cells, selecting a memory read reference level according to the first read reference level, and reading the non-volatile memory array cells.

    摘要: The present invention is a method, circuit and system for erasing one or more non-volatile memory ("NVM") cells in an NVM array or array segment, According to some embodiments of the present invention, one or more erase pulse parameters may be associated with each of a number of array segments within an NVM array. Separate erase pulse parameters may be associated with anywhere from one to all of the array segments within an NVM array. According to some embodiments of the present invention, a characteristic of an erase pulse (e.g. pulse amplitude, pulse duration, etc.) applied to one or more MVM cells within art array segment may be at least partially on one or more erase pulse parameters associated with the given array segment.
