ABSTRACT:
A semiconductor memory device including a nonvolatile random access memory cell constituted by a combination of a static random access memory cell or a dynamic random access memory cell and a floating circuit element, is disclosed.
In the device, the circuit constitution, the application of writing voltage, and the like, are improved. Thus, the number of the circuit elements, particularly the number of floating gate circuit elements, is reduced. As a result, the cell area can be decreased, high integration of the device can be increased. In addition, improvement of the circuit configuration increases the discretion allowed in the layout design, and the plurality of applications of the write voltage improves the storage efficiency.
