SIGNAL PROCESSING CIRCUIT AND METHOD FOR DRIVING THE SAME |
摘要 |
<p>It is an object to provide a memory device for which a complex manufacturing process is not necessary and whose power consumption can be suppressed and a signal processing circuit including the memory device. In a memory element including a phase-inversion element by which the phase of an input signal is inverted and the signal is output such as an inverter or a clocked inverter, a capacitor which holds data and a switching element which controls storing and releasing of electric charge in the capacitor are provided. For the switching element, a transistor including an oxide semiconductor in a channel formation region is used. The memory element is applied to a memory device such as a register or a cache memory included in a signal processing circuit.</p> |
