1. A resistive memory array, comprising:

  • a plurality of resistive memory units arranged in rows and columns, wherein each of the resistive memory units comprises a first memory cell, and a second memory cell disposed under and electrically connected in series with the first memory cell, wherein each of the resistive memory units includes;

    a first solid electrolyte, being a part of the first memory cell;

    a second solid electrolyte, being a part of the second memory cell; and

    an oxidizable electrode, formed between the first solid electrolyte and the second solid electrolyte,wherein the first solid electrolyte and the second solid electrolyte are made of a transition metal oxide or a material containing at least one chalcogenide element;

    a plurality of word lines, wherein each of the word lines is coupled to the first memory cells of a row of the resistive memory units; and

    a plurality of bit lines, wherein each of the bit lines is coupled to the second memory cells of a column of the resistive memory units.
