    摘要: A memory device in a 3-D read and write memory includes memory cells. Each memory cell includes a resistance-switching memory element (RSME) in series with a steering element. The RSME has first and second resistance-switching layers on either side of a conductive intermediate layer, and first and second electrodes at either end of the RSME. The first and second resistance-switching layers can both have a bipolar or unipolar switching characteristic. In a set or reset operation of the memory cell, an electric field is applied across the first and second electrodes. An ionic current flows in the resistance-switching layers, contributing to a switching mechanism. An electron flow, which does not contribute to the switching mechanism, is reduced due to scattering by the conductive intermediate layer, to avoid damage to the steering element. Particular materials and combinations of materials for the different layers of the RSME are provided.

    摘要: A non-volatile memory device contains a three dimensional stack of horizontal diodes located in a trench in an insulating material, a plurality of storage elements, a plurality of word lines extending substantially vertically, and a plurality of bit lines. Each of the plurality of bit lines has a first portion that extends up along at least one side of the trench and a second portion that extends substantially horizontally through the three dimensional stack of the horizontal diodes. Each of the horizontal diodes is a steering element of a respective non-volatile memory cell of the non-volatile memory device, and each of the plurality of storage elements is located adjacent to a respective steering element.
