A manufacturing method is provided for a light modulation device that improves utilization efficiency of light. After forming a first reflective layer using a metallic material such as Pt or the like, on a substrate, a light modulating film is formed using an electro-optic material in which refractive index changes in accordance with an applied electrical field. After that, planarization is carried out so that irregularities on an upper surface of the light modulating film are less than or equal to 1/100 of the wavelength of light incident on the light modulation device. A transparent electrode is then formed using ITO, ZnO, or the like, on the light modulating film, and a second reflective layer including a dielectric multilayer is formed.

To provide a logical operation circuit and a logical operation device which can performs a logical operation using a ferroelectric capacitor. The area ratio between the ferroelectric capacitors CF1 and CF2 are set such that the potential difference Vdef between voltages Va1 and Va0 is as large as possible, and a transistor MP has a threshold voltage Vth which is about ½·(Va0+Va1). Thus, the ON/OFF operation margin of the transistor MP can be significantly large. As a result, a reading process can be performed at a high speed without using an amplifying circuit such as a sense amplifier. Also, the logical operation circuit and the logical operation device can be highly integrated with ease since no sense amplifier is used.

A switch circuit that is simple in constitution and capable of reliably controlling a switch cell is provided. Since the, gate terminal G1 of a transistor M1 in a switch cell SC is connected only to the terminal 37 of a transistor M2, when the transistor M2 is set to off, the moving path of the charge accumulated at the gate G1 of the transistor M1 is shut off. Consequently, even if the transistor M2 is set to an on state and immediately set back to an off state, the transistor M1 remains for some period of time in an on or off state corresponding to the switching data given through a bit line BL. It is possible to cause the transistor M1 to remain in an on or off state for a specified period of time without disposing a specific circuit for temporary storing the switching data.

To provide a memory device with a function to perform an operation and a method of performing an operation and storage which can save space and cost and which can start, immediately after the power source is recovered, the processing which was being performed at the time of power failure. A memory cell MC can store two independent data sets; DRAM data (volatile data) and FeRAM data (non-volatile data). Thus, the number of memory cells can be reduced to a half. Also, the DRAM data to be used in the next operation of the two data sets which have been read out for the previous operation are temporarily held in a hold circuit 21 of an operation unit OU and then written back into the memory cell MC in a non-volatile manner as new FeRAM data for preparation of the next operation. Thus, even when the power source is shut down by an unexpected trouble, the data necessary for the next operation are not lost.
