Abstract
A memory circuit includes: a bistable circuit (30) that writes data; nonvolatile elements (MTJ1, MTJ2) that store the data written in the bistable circuit into the nonvolataole element in a nonvolatile manner, and restore the data stored in a nonvolatile manner into the bistable circuit; and a determining unit (50) that does not store the data written in the bistable circuit into the nonvolatile elements when the data in the bistable circuit is the same as the data in the nonvolatile elements, but stores the data in the bistable circuit into the nonvolatile elements when the data in the bistable circuit is not the same as the data in the nonvolatile elements.
