Abstract
PURPOSE:To shorten a data writing time by mutually transferring data between a non-volatile storing part having a pair of mutually cross connected floating gate transistors and a random access storing part having a pair of mutually cross connected inverter transistors. CONSTITUTION:The random access storing part constituted by mutually cross connecting two inverters Q1-Q4 like a CMOS inverter and the non-volatile storing part having a pair of cross connected floating gate transistors Q5, Q6 are used to connect both the storing parts so as to mutually transfer the data. The data written in this random access storing part from an external circuit is transferred to the non-volatile storing part at a proper time such as before the power source of a computer system is interrupted and the stored data can be held after the power source of the system is interrupted. By transferring the data, it is restored, the data is read to the external circuit or the data is written from the external circuit. Thereby, the data writing time is remarkably reduced.
