Abstract

A semiconductor switching element comprised by a high resistivity polycrystalline silicon resistor whose resistance irreversibly decreases to a small value at a threshold voltage upon the voltage across the resistor reaching the threshold voltage. A semiconductor memory device is constituted by using the switching element as a memory cell and a semiconductor gate element for controlling the current flowing through the semiconductor switching element.
