Logical calculation circuit, logical calculation device, and logical calculation method |
摘要 |
A logical calculation circuit capable of storing data, and performing logical calculations with high reliability and high speeds are provided. The residual polarized state s' of a load ferroelectric capacitor Cs' is actively changed so that the residual polarized state s' of a load ferroelectric capacitor Cs' is opposite to the residual polarized state s of a storage ferroelectric capacitor Cs. In the case a reference potential is made c=0 in the calculation operation, even if the second data to be calculated x=1 is given to the storage ferroelectric capacitor Cs in the residual polarized state s (the first data to be calculated)=0, the ferroelectric capacitor Cs does not reverse in polarity. Even with combinations other than s=0 and x=1, the ferroelectric capacitor Cs does not reverse in polarity. Difference is great between a potential VA=VA(0) occurring at a coupling node when x=1 is given to the ferroelectric capacitor Cs of s=0 and a potential VA=VA(1) occurring at the coupling node when x=1 is given to the ferroelectric capacitor Cs of s=1.
