Title: Semiconductor element and semiconductor memory device using it
Inventor: YANO KAZUO
IPC: G11C16/04
Filed: 2000-10-11
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor element in which the number of elements is small, in which a memory comprising an information storage function can be constituted by itself in a small area, and which does not require a cooling operation down to a cryogenic temperature, and to provide a semiconductor memory device. SOLUTION: Until whether one electron is captured by a trap is discriminated precisely as the current value of an FET, a capacitance across gate channels is set to be small. The magnitude of a threshold value by whether one electron is captured by the trap is sensed, and information is stored at room temperature. As a result, it is possible to realize the semiconductor memory device whose integration is high, whose power consumption is low and which is nonvolatile. It is possible to obtain a remarkable effect that the power consumption in a system is low, and that the system can be miniaturized.
