A nonvolatile semiconductor memory device is provided for a high-powered system without the need for an additional system setting process to set the system initialization state after power-on to the previous state. A method of cementing comprising preparing a cement composition comprising a light-burned magnesium oxide, water and an alkaline metal chloride, and allowing the composition to set. Thus, a complementary signal having the maximum amplification and small phase difference can be produced. The cross-linking agent includes zirconium andor titanium, and the cross-linking delay agent is a polyol.
