Abstract
It is an object to provide signal storing circuits and related devices capable of storing resulting data even when the power supply thereto is suspended, and to provide the signal storing circuit which consumes less power. A logic processing circuit,comprises a combined logic block CB and a latching block LT. The latching block LT includes a line,for passing the resulting data OUT outputted by the logic block CB. A circular signal path (feedback loop) including a line,and another line,overlaps a part of the line,. An inverter circuit INV,made of a ferroelectric transistor is provided to the line,. In this way, the resulting data OUT existing on the line,can be stored in ferroelectrical manner and the data right before the shut-off of the power supply can be reproduced on the line,with the recovery of the power supply. In order to suppress the power consumption, a power control portion,switching the power supplied to the latching block LT is provided to the processing circuit
