Abstract:
1. A computation processing circuit which executes logic computation based upon input data and data stored in memory, comprising: a ferroelectric capacitor which includes a first terminal and a second terminal, and which has a function as memory; a driver circuit which switches a voltage to be applied to the first and second terminals of the ferroelectric capacitor according to the input data; and a sense amplifier which outputs computation results according to the voltage that occurs at the first terminal or the second terminal, wherein the driver is configured to apply a voltage to the first terminal and to set the second terminal to a high-impedance state when the input data is at a first level, and to apply a voltage to the second terminal and to set the first terminal to a high-impedance state when the input data is at a second level.
