Abstract
A phase-change-memory cell is provided which comprises two insulated regions formed in a first phase-change material connected by a region formed in a second phase-change material. The crystallization temperature of the second phase-change material is below the crystallization temperature of the first phase-change material. By locally changing the material properties using a second PCM material, which switches phase at a lower temperature, a localized “hot spot” is obtained.
Claims10
A phase-change-memory cell comprising two insulated regions formed in a first phase-change material connected by a region formed in a second phase-change material whereby a crystallization temperature of the second phase-change material is below a crystallization temperature of the first phase-change material.
