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. |
