Abstract

A method of fabricating a nano-scale resistance cross-point memory array includes preparing a silicon substrate; depositing silicon oxide on the substrate to a predetermined thickness; forming a nano-scale trench in the silicon oxide; depositing a first connection line in the trench; depositing a memory resistor layer in the trench on the first connection line; depositing a second connection line in the trench on the memory resistor layer; and completing the memory array. A cross-point memory array includes a silicon substrate; a first connection line formed on the substrate; a colossal magnetoresistive layer formed on the first connection line; a silicon nitride layer formed on a portion of the colossal magnetoresistive layer; and a second connection line formed adjacent the silicon nitride layer and on the colossal magnetoresistive layer.
