Abstract
Provided is a phase-change RAM containing a substrate, a lower electrode, a phase-change material, an upper electrode and a thermal dissipation layer, wherein the thermal dissipation layer contains an aluminum-nitride thermal dissipation layer having a high heat conductivity, and the lower electrode contains a titanium-nitride electrode which generates a great amount of heat generated using a small amount of current and has a low heat conductivity, whereby heat generated between the phase-change material and the electrode is not transferred to the interior of a device but fast dissipated to the exterior thereof, so as to enable a high speed operation using low current and improve reliability of the device.
