<p><P>PROBLEM TO BE SOLVED: To provide constitution of a thin film magnetic substance storage device which can store program information efficiently and stably. <P>SOLUTION: Each of program cells and memory cells comprises the same magnetic storage part, the program cell comprises a state change part. Therefore, the program cell has constitution in which the state change part is added to the structure similar to the memory cell. That is, same design as the memory cell can be applied for the magnetic storage part or the like, and the efficient program cell can be arranged. Also the state change part is changed to a fixed state based on electrical change. Therefore, the state change part can store program information stably without allowing program information to be rewritten by magnetic noise or the like. <P>COPYRIGHT: (C)2004,JPO</p> |
