Abstract
It is an object of the present invention to provide a memory device with processing function using less transistors, and capable of operating with simple operation and allows its operation with less trouble. Each of W cells 34 includes a ferroelectric capacitor CF. One end 40 of the ferroelectric capacitor CF is connected to one of data lines D through a transistor T1. The one end 40 of the ferroelectric capacitor CF is connected to an inner data line MW through a transistor T2. The structure of the Q cells 36 is almost the same as that of the W cells 34. Both readout/writing operations of data from the outside of the device are performed by using the data line D. Data read out from both the W cell 34 and the Q cell 36 is sent to the adder 28 and added thereby, and the resultant data of the addition is written to the Q cell 36 through a buffer circuit 32. The memory device with processing function can be realized with a simple structure by using ferroelectric capacitors CF.
