SYSTEM AND METHOD FOR IDENTIFYING OPERATING TEMPERATURES AND MODIFYING OF INTEGRATED CIRCUITS

摘要

Aspects of the present disclosure include a computer-implemented method for identifying an operating temperature of an integrated circuit (IC), the method including using a computing device for: applying a test voltage to a test circuit embedded within the IC, the test circuit including a phase shift memory (PSM) element therein, wherein the PSM element crystallizes at a crystallization temperature from an amorphous phase having a first electrical resistance into a crystalline phase having a second electrical resistance, the second electrical resistance being less than the first electrical resistance; and identifying the IC as having operated above the crystallization temperature in response to a resistance of the test circuit at the test voltage being outside of the target operating range.
