Patent ID: 7687838

Claim:
A resistive memory device comprising: a memory part having a bottom electrode and a ferroelectric layer sequentially formed on a first substrate; a probe part having an array of resistive probes arranged on a second substrate, the resistive probes comprising tips which face the ferroelectric layer such that they can write and read data on the ferroelectric layer; and a binding layer which grabs and fixes the resistive probes on the ferroelectric layer, wherein each of the resistive probes comprises: a resistive region at the tip, a resistance of which changes according to the direction of remnant polarization in a domain of the ferroelectric layer corresponding to the tip; and a first electrode region and a second electrode region, which are separated from each other on inclined surfaces of the probe and have the resistive region interposed therebetween, the first and the second electrode regions being used to detect the resistance of the resistive region when reading data, wherein the resistive region is disposed inside the binding layer for the binding layer to grab and fix the resistive probes on the ferroelectric layer, and wherein the first and second electrode regions are not disposed inside the binding layer wherein the binding layer comprises at least one of a polymer layer and adhesive resin that insulate and shield the ferroelectric layer from charged particles and atmospheric humidity.
