A bit line is connected, via a first pMOS transistor, to a first node whose potential is set at a prescribed negative voltage in advance. The gate voltage of the first pMOS transistor is set at a constant voltage that is slightly lower than its threshold voltage. During a read operation, a current that flows into the bit line from a memory cell in accordance with a residual dielectric polarization value of a ferroelectric capacitor always leaks to the first node, whereby the potential of the first node increases. The logical value of data stored in the memory cell is judged on the basis of a voltage increase at the first node. Since no control circuit for keeping the potential of the first node at the ground potential during a read operation is necessary, the layout size and the power consumption of a ferroelectric memory can be decreased.

An output node NO is, on one hand, connected through a PMOS transistor TP1 and an NMOS transistor TN1 to ground, and on the other hand, connected through a PMOS transistor TP2 and an NMOS transistor TN2 to a node N6 which is selectively set to ground and VDD. The output node NO is connected through a capacitor C1 to the input of a driving inverter 11 in order to step-up or step-down the voltage of the output node NO. When the output node NO is set to −1V, the control circuit 10 turns off the PMOS transistors TP1 and TP2. It is also allowed to connect the output node through a first PMOS transistor to a second PMOS transistor whose back gate is connected to a power supply voltage VDD, and to connect the back gate of the first PMOS transistor to one end of a current path thereof on the side of the second PMOS transistor.

摘要:
The present invention provides a non-volatile memory circuit that can easily read and write. Especially, the present invention is effective to storage multi-value or analog value. The present invention has a storage transistor Nc with a floating gate and a feedback transistor Nf with a floating gate whose source are connected commonly and a load circuit is provided to the drain side of both transistors. A negative feedback circuit is provided between the drain of the storage transistor Nc and the floating gate of the feedback transistor Nf. An output transistor P2 is a preferable example of the negative feedback circuit, whose gate is connected to the drain of the storage transistor and which generates a voltage corresponding to that gate voltage at an output terminal. This output terminal and the floating gate of the feedback transistor are connected. A memory circuit of such a configuration operates so that the voltage corresponding to the charge in the floating gate of the storage transistor Nc and the output voltage of the output terminal OUT become the same. Therefore, the voltage of the floating gate of the storage transistor can be directly detected.
