摘要： High device reliability, a reduction in power consumption, and a high operation speed are achieved. When a predetermined bias voltage is applied between a source 1 and a drain 2 to change a gate voltage, a current discretely flows between the source 1 and the drain 2 in accordance with quantized electrostatic energy levels in an island electrode 3. The switching ON/OFF of the current between the source 1 and the drain 2 in this case is enabled by applying ½-electron charge to a gate. When the gate voltage induces polarization in a ferroelectric layer 6, its electric field is applied to the island electrode 3. The current between the source 1 and the drain 2 in this case can be measured with high sensitivity. Charge holding is carried out by the polarization in the ferroelectric layer 6, and stored data can be held even if power supply is cut off.
