    摘要: A selection device, non-volatile memory cell, and method of fabricating the same. The selection device employs an oxide laminate structure including a tunneling oxide layer and a metal-cluster oxide layer between first and second electrodes, enabling a high selection ratio and sufficient on-current density to allow program data recordation in a memory cell at relatively low voltage. The non-volatile memory cell includes the selection device electrically connected to a resistive random access memory device, including a resistance change layer, enabling suppression of current leakage from a non-selected adjacent memory cell in an array structure. In the method of fabrication, a tunneling oxide layer is formed by depositing and oxidizing a metal layer to control oxygen vacancy density in the metal-cluster oxide layer, and an interface oxide layer is formed in the tunneling oxide layer by doping of metal-clusters in the metal-cluster oxide layer, improving on-current density of the selection device.

    摘要: Provided are resistive memory devices and methods of fabricating the same. The resistive memory devices and the methods are advantageous for high integration because they can provide a multilayer memory cell structure. Also, the parallel conductive lines of adjacent layers do not overlap each other in the vertical direction, thus reducing errors in program/erase operations.

    摘要: Methods of forming diode structures for use in memory cells and memory arrays, such as resistive random access memory (RRAM). The methods include forming a first electrode by chemisorbing a graphite material (e.g., graphene) on a conductive material. A low-k dielectric material may be formed over surfaces of the first electrode exposed through an opening in a dielectric material overlying the first electrode, followed by formation of a high-k dielectric material over the low-k dielectric material. A remaining portion of the opening may be filled with another conductive material to form a second electrode. The first and second electrodes of the resulting diode structure have different work functions and, thus, provide a low thermal budget, a low contact resistance, a high forward-bias current and a low reverse-bias current. A memory cell and a memory array including such a diode structure are also disclosed.
