Abstract: PURPOSE: A semiconductor memory device and a data processing device are provided to enable performing a high speed rewrite with a decreased area and a semiconductor memory having a high capacity with a small area or high speed operation and low power consumption characteristics. CONSTITUTION: A peripheral circuit(51) such as a sense amplifier and driver is built on a silicon substrate surface, and a memory cell array(52) is provided thereon with an insulator film interposed therebetween. According to this construction, a small-area memory device can be produced as compared with the case where the memory cell array and the peripheral circuit are formed on the same plane. Also, this construction is suited for fast operation because the memory cell array and the peripheral circuit can be connected by short conducting lines. The memory cell array on the insulator film is not limited to semiconductor memories, but may be memories made of other materials such as MRAM(magnetic random access memory). The MRAM stores information by utilizing a phenomenon that the resistance of a conductor which consists of stacked two magnetic films changes or a tunnel current between the magnetic films changes, when the magnetization directions of the magnetic films are parallel or anti-parallel.
