  • System and method for multi-bit flash reads using dual dynamic references
    Patent number: 7103706
    Abstract: A system and methodology is provided for proper reading of multi-bit memory cells in a memory device. A first reference cell and a second reference cell is employed to determine an average dynamic reference value. The average dynamic reference value is determined by reading a programmed bit of the first reference cell and reading an unprogrammed or erased bit of a second reference cell to determine an average dynamic reference value. The average dynamic reference value can be utilized to determine whether data cells are in a programmed state or in an unprogrammed state.
