Abstract
A radial memory device includes a phase-change material, a first electrode in electrical communication with the phase-change material, the first electrode having a substantially planar first area of electrical communication with the phase-change material. The radial memory device also includes a second electrode in electrical communication with the phase-change material, the second electrode having a second area of electrical communication with the phase-change material, the second area being laterally spacedly disposed from the first area and substantially circumscribing the first area. Further, a method of making a memory device is disclosed. The steps include depositing a first electrode, depositing a first insulator, configuring the first insulator to define a first opening. The first opening provides for a generally planar first contact of the first electrode. The method further including the steps of depositing a phase-change material, depositing a second insulator, configuring the second insulator, depositing a second electrode having a second contact laterally displaced from said first contact, and configuring said second electrode.
