In the memory operation, dataretentiontimedeterminesrefreshfrequencyandisone ofthemostimportantmemorymerits.Inthispaper,wehave systematicallyinvestigatedthe Z2FET retention time based on a newly proposed characterization methodology. It is found that the degradation of HOLD “0” retention time originates from the gated-silicon on insulator (SOI) portion rather than the intrinsic-SOI region of the Z2FET. Electrons accumul
