The reduction of the power consumption is becoming more essential for portable systems. A powering down scheme is very useful to reduce power consumption of LSIs. The scheme needs to keep logic state, so several latch circuits have been reported. However, these methods require large additional circuit or special manufacturing process. A non-volatile latch with ferroelectric capacitors is simple and smart way [1], and its area penalty is very small. The non-volatile device needs no power supply for data keeping, Moreover, a dynamic reconfigurable logic can be possible by using the non-volatile latch as non-volatile switches.
