摘要:
A field-effect semiconductor element implemented with a fewer number of elements and a reduced area and capable of storing data by itself without need for cooling at a cryogenic temperature, and a memory device employing the same. Gate-channel capacitance (C gc ) is set so small that whether or not a trap (7) captures one electron or hole can definitely and distinctively be detected in terms of changes of a current of the semiconductor FET element. By detecting a change in a threshold voltage of the semiconductor element brought about by trapping of electron or hole in the trap, data storage can be realized at a room temperature.
摘要(中):
一种场效应半导体元件,其具有较少数量的元件和减小的面积并且能够自身存储数据,而不需要在低温下进行冷却;以及采用该半导体元件的存储器件。 栅极沟道电容(Cgc)被设定得很小,以致捕获器(7)捕获一个电子或空穴是否可以根据半导体FET元件的电流的变化来明确且明显地被检测。 通过检测通过在阱中捕获电子或空穴而导致的半导体元件的阈值电压的变化,可以在室温下实现数据存储。
