  • Patent number: 7701779
    Abstract: A method for programming one or more reference cells is described. The reference cell is programmed a predetermined amount, its program state is sensed relative to a prescribed cell on the same die (e.g., a memory cell or a golden bit cell), and the programming process continues until the reference cell fails a preselected read operation. In one preferred embodiment, the memory cell used during the reference cell programming process is the cell in the memory array having the highest native threshold value. In another preferred embodiment, the memory cell used during the reference cell programming process is a native cell that is on-board the die containing the memory array, but not a cell within the memory array.

  • Publication number: 20070036007
    Abstract: A method for programming in parallel reference cells to be used for operating other cells of a memory cell array, the method including: a) reading each of the reference cells of a memory cell array with a sense amplifier, the sense amplifier providing an output indicative of a programmed state of the reference cell relative to another bit in the array, b) reading each of the reference cells of a memory cell array with a sense amplifier while using read conditions to determine if the reference cells have reached a target level, c) determining if a programming pulse should be applied to the reference cell by comparing the output of the sense amplifier to a predefined target “0” or “1”, d) setting a buffer bit, corresponding to the output of the sense amplifier, in a sticky bit buffer to a first logical state if the reference cell needs to be programmed, and not changing a logical state of the buffer bit if the reference cell does not need to be programmed, e) performing steps a)-d) for a desired address range i
