    摘要: In a non-volatile memory system, a plurality of main memory cells for storing data is arranged in a data cell array and a plurality of reference memory cells is arranged in a reference cell array. The reference cell array includes first reference word lines connected to first reference memory cells and extending, second reference word lines connected to second reference memory cells and extending alternately with the first reference word lines, reference bit lines to which the first and the second reference memory cells are alternately connected in a line and a combined cell having a pair of the first and second reference memory cells and generating a reference signal for processing the data. The first and the second reference memory cells have different cell characteristics. The stability of the reference signal is improved irrespective of the differentiation of the first and the second reference memory cells.

    摘要: A semiconductor memory device includes a main cell array region, a first redundancy cell array region and a first dummy cell array region that are formed at one side of the main cell array region, and a second redundancy cell array region and a second dummy cell array region that are formed at the other side of the main cell array region. The first redundancy cell array region includes a first redundancy bitline, and the first dummy cell array region includes first dummy bitlines. The second redundancy cell array region includes a second redundancy bitline, and the second dummy cell array region includes second dummy bitlines. The first and second redundancy cell array regions are disposed closer to the main cell array region than the first and second dummy cell array regions.
