A static random access memory and method of evaluating the same for cell stability, write margin, and read current margin. The SIWA protocol uses existing wireless network messaging to exchange information between wireless devices and a network server, referred to herein as an Intelligent Service Manager. Consequently, it is possible to reduce an energy input amount to a base metal, thereby suppressing burn-through in welding of a thin plate. The second circuit is configured to receive data via the network and receive a current that corresponds to the signal via the second electrode based on the data. Additionally, a first interlayer insulating film and a second interlayer insulating film are disposed between the gate electrode and the second wirings so as to decrease a parasitic capacitance.
