SEMICONDUCTOR MEMORY ELEMENT AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a semiconductor memory element that performs data recording operation with a low current, because the element can transmit the quantity of heat required for the phase transition of a chalcogenide substance layer with a small quantity of current, and also to provide a method of manufacturing the element.

SOLUTION: The semiconductor memory element is provided with a heat generator disposed between a transistor and a data storing section, and metallic wiring connected to the data storing section. The data storing section contains the chalcogenide substance layer which stores data by causing phase transition when the heat generator generates heat.
