Abstract:
Embodiments are directed to a static random access memory (SRAM) device that prevents burn-in of potentially sensitive information. After an SRAM device is fabricated in a semiconductor material, a heating wire is placed in the layers above portions of the SRAM device. By applying current to the heating wire, a certain temperature is reached for a certain amount of time, and the burn-in of the SRAM is prevented. Other embodiments are also presented.
