Method for measuring optoelectronic memory device

Abstract

A method for measuring an optoelectronic memory device, includes: grounding a source electrode of the optoelectronic memory device; applying a drain electrode voltage to a drain electrode of the optoelectronic memory device and measuring a first current at the drain electrode; using an optical source to illuminate the optoelectronic memory device and measure a first and a second current at the drain electrode; and comparing the sizes of the first current and the second current so as to judge the functional parameters of the optoelectronic memory device.
