DATA HOLDING DEVICE AND LOGIC OPERATION CIRCUIT USING THE SAME |
| 摘要 |
A data holding device includes a loop structure unit configured to hold data using a plurality of logic gates connected in a loop shape, a nonvolatile storage unit including a plurality of ferroelectric elements, the nonvolatile storage unit configured to store the data held in the loop structure unit in a nonvolatile manner using hysteresis characteristics of the ferroelectric elements, and a circuit separation unit configured to electrically separate the loop structure unit and the nonvolatile storage unit. The ferroelectric elements of the nonvolatile storage unit are surrounded by a dummy element smaller in width than the ferroelectric elements. |

1. A data holding device, comprising:
a loop structure unit configured to hold data using a plurality of logic gates connected in a loop shape; a nonvolatile storage unit including a plurality of ferroelectric elements, and configured to store the data held in the loop structure unit in a nonvolatile manner using hysteresis characteristics of the ferroelectric elements; and a circuit separation unit configured to electrically separate the loop structure unit and the nonvolatile storage unit, wherein the ferroelectric elements included the nonvolatile storage unit are surrounded by a dummy element, and a width of the dummy elements is smaller than a width of the ferroelectric elements. |
