Abstract
Devices controlling a phase change storage element and methods for increasing reliability of a phase change storage element. The invention introduces a first operation mode and a second operation mode. A reference phase change storage element is forced a write current for an ideal conduction period in the first operation mode. In the second operation mode, the invention generates a proper conduction period based on the resistance of the reference phase change storage element, and forces the write current into the controlled phase change storage element for the proper conduction period.
