Adder
A circuit in which a storage function and an arithmetic function are combined is proposed by using a transistor with low off-state current for forming a storage element. When the transistor with low off-state current is used, electric charge can be held, for example, in a node or the like between a source or a drain of the transistor with low off-state current and a gate of another transistor.
