Abstract
The first fire voltage of amorphous memory devices are reduced by forming the storage element of two layers, the first being in the crystalline state and the second being the amorphous state. The process deposits a first layer of switchable material and raises the temperature to crystallize the first layer. The wafer is then cooled and the remainder of the switchable material to form the storage element is deposited in an amorphous state.
