Abstract:
A method of operating a semiconductor device that is powered by a first power supply potential can include detecting a change in at least one voltage window signal, the voltage window signal indicates a predetermined voltage window in which a potential of the first power supply potential is located; latching the at least one voltage window signal to provide at least one latched voltage window signal; and generating at least one assist signal in response to at least one latched voltage window signal; wherein the at least one assist signal alters a read operation or a write operation to a static random access memory (SRAM) cell as compared to operations without the assist signal.
